6 Best Ovulation Tests to Find Your Fertile Days, Based on Our Testing

The Bump takeaway: The Clearblue Advanced Digital Ovulation Test is the Best of The Bump winner for best basic ovulation insights. By tracking two hormones and translating results into simple digital symbols, it offers a clear view of your fertile window that doesn't overwhelm you with data.

Trying to conceive can be an overwhelming process, and sometimes you don’t want ovulation tests that add to the information overload. After all, reams of numerical data can be overwhelming for those who are just starting out, or frustrating to those who just need a heads up that their most fertile days are approaching. If you’re in the early stages of trying for a baby, or simply want an easy-to-read ovulation test, the Clearblue Advanced Digital Ovulation Test may be the best fit for you. This is the product I used to track ovulation when I was trying to conceive, and I loved the no-frills experience it provided––just clear answers.

Data collection
Our tester Lindsay appreciated that the test can identify a wider fertile window than traditional LH-only tests because it tracks two hormones instead of one––luteinizing hormone (LH) and estrogen. “There are some ovulation predictor kits that measure other markers of menstrual cycle changes and ovulation, including estrogen, which steadily increases from the start of menstruation to mid cycle, giving you an even earlier ‘heads-up’ on when you are approaching your most fertile window,” says Dr. Sekhon.

Clearblue also offers an app that lets users log ovulation test results and track cycle patterns. Lindsay tested the app and found it to be user-friendly, visually appealing and packed with helpful information.

How it works
This urine test looks at two hormones: LH, which surges just before ovulation, and estrone-3-glucuronide (E3G)—the form of estrogen found in urine—which rises shortly before the LH surge. By tracking both hormones, the Clearblue Advanced Digital Ovulation Test can identify more fertile days than a traditional LH-only test.

A flashing smiley face appears during high fertility, followed by a static smiley face when peak fertility is detected. Once you receive a peak fertility result, the static smiley face will remain for 48 hours and you no longer need to test during your current cycle. An empty circle indicates low fertility, and you should continue testing daily.

In terms of accuracy, I found that Clearblue Advanced Digital’s peak fertility results aligned with the other fertility-tracking methods I was using.

How easy is it to use?
To use, simply hold the absorbent tip in your urine stream for three seconds and wait five minutes for your digital results. If you prefer not to pee directly on the stick, you can also dip the test into a collected urine sample for 15 seconds before waiting for the results.

I loved the simplicity of this test. Unlike other ovulation tests that require interpretation of lines or color changes, the Clearblue Advanced Digital Ovulation Test clearly displays an icon to indicate fertility status. Lindsay also appreciated the reusable test holder, which you insert the test stick into for your results.

Our survey respondents also gave this test high marks for ease of use, with several stating that the clarity of results was a major plus. “This kit was recommended by the fertility specialist, and it worked well for us. I used this on my own and got pregnant successfully,” says survey respondent Samantha. Similarly, the Clearblue Advanced Digital test was the ovulation predictor of choice for The Bump’s content director, Ashlee Neuman, who conceived the first month of using it—twice!

The Bump takeaway: The Inito Starter Kit is the Best of The Bump winner for advanced fertility insights. By tracking four hormones and translating the results into clear fertility ratings and detailed charts, it delivers in-depth cycle data that isn't hard to understand.

Whether you have irregular cycles or simply want more detailed information about your fertility, an ovulation tracker that provides deeper insights might fit your needs.

I tested the Inito Starter Kit and loved the detailed information about my cycle that it provided. Even better, I found it to be extremely easy to use and understand. The app provides step-by-step instructions, including a built-in timer, each time you use a testing strip. Once your test is finished, a very clear, easy-to-read result pops up in the app telling you whether you are at low, high or peak fertility.

The quick-read fertility status ratings are great when you just want to see where you are in your cycle at a glance. But for those who are looking for more detailed insights, the app offers plenty of data to inspect. I appreciated that it keeps a log of test dates, times and results, and groups the results by cycle so it’s easy to go back and reference later.

The hormone chart in the app is even color-coded by hormone and fertility status. It’s a clear, visual way to see your results, which was especially helpful when testing in the morning––I could quickly see my result and know that I could come back later to dig deeper.

Data collection
The Inito Starter Kit tests for four hormones: E3G, LH, pregnanediol glucuronide (PdG) and follicle-stimulating hormone (FSH). You can view numerical values for each hormone and the app provides reference ranges for different phases of the cycle. You can also add additional details like your basal body temperature (BBT) and ovulation symptoms.

This more detailed hormone tracking may be especially useful for people who find traditional LH-only tests difficult to interpret. “For people with irregular cycles or conditions like PCOS, ovulation tests can be less reliable. This is because PCOS is often associated with elevated baseline LH levels, which can cause ovulation predictor kits to show positive results even when ovulation isn’t actually happening,” says Dr. Sekhon. By tracking changes in four hormones rather than looking at the LH surge alone, Inito provides a more complete picture of hormone patterns throughout the cycle.

How it works
This urine test shows you up to six fertile days by tracking four hormones: E3G, LH, PdG and FSH—this is the highest number of any test we looked at. Most standard ovulation kits track LH, but each of the other hormones opens the door to deeper insights and a wider fertility window:

• PdG. By tracking PdG for a sustained rise after the LH surge, Inito is able to confirm that ovulation actually happened. This is important, Dr. Sekhon explains, because some people can have multiple LH surges within the same cycle, so they're not a 100 percent accurate predictor of ovulation.
• FSH: This hormone usually spikes right before an egg is released by the ovary, so tracking it can help verify ovulation.
• E3G: This hormone allows the Inito to identify the fertile window earlier than an LH-only test that primarily detects the surge shortly before ovulation. This is important because sperm can survive in the reproductive tract for up to five days, so identifying the fertile window before ovulation gives you more time to strategically time intercourse.

How easy is it to use?
The Inito Starter Kit is a urine test. It uses a disposable strip, loaded into a wand that connects to your home WiFi signal. This is an important note, because you have to use a WiFi connection—during testing, my Wi-Fi went out after I had already dipped a wand and I wasn’t able to connect the reader and complete the test. I ultimately wasted the strip and had to wait to test again.

The wand comes with a small cup with a “max fill” line that you use to collect your first urine of the day. You then follow along step-by-step in the app, which provides you a timer for dipping the wand into the urine. Cap the wand to prevent mess, and insert it into the set's hormone reader, which clicks when inserted completely. Once the app connects to the reader, it will start a timer and begin analyzing your data. After 15 minutes, the test is complete and your results are displayed in your app.

The nice thing about this process is that once you've got the wand in the reader, you can set it and forget it. Once I inserted the wand, I would take a shower and get ready for work knowing that my results would be ready in my app when I was done.

When the analysis is ready, an immediate reading of low, high or peak fertility comes up in the app in bold letters. From there you can go deeper into the information, with a hormone chart that you can use to review your specific hormone levels and see where you are in your cycle.

One important (and welcome) note about the Inito: In past years, the major pain point we identified was that it could only be used with iOS devices. As of this year, this is no longer the case—the updated wireless reader works with both iOS and Android, making the system accessible to far more users.

The Bump takeaway: Modern Fertility Ovulation Test Strips are the Best of The Bump winner for best ovulation test strips. The color-coded results are easy to read on their own, while the free app scans and charts your LH tests over time for a more detailed look at your surge.

Ovulation test strips are one of the simplest ways to track LH, but interpreting a row of pink lines isn’t always so simple. Modern Fertility Ovulation Test Strips add helpful tracking and interpretation tools to the traditional strip-test experience. The strips come with a companion app (available only to iOS users) that tracks your ovulation test results, provides insight into your cycle and fertility and offers calendars for predicting your next period and fertility window.

Our product tester, Lindsay, especially appreciated the additional tracking tools, telling us, "The app will offer you a wealth of insight into your cycle." But if you’d prefer to keep things simple, you can just compare the test strip to the color-coded chart on the back of the packaging—a small but useful feature, and not one you find on most test strips!

How it works
These strips measure the LH in your urine to pinpoint your most fertile days. Dip a test strip into an afternoon urine sample for 10 seconds, lay it flat on the included color-coded chart, and wait five minutes for the results. Then compare the test line to the color-coded chart on the wrapper to estimate your LH level. The darker the line, the more LH is present in your urine and the closer you may be to an LH surge.

You can manually track your results or use the free Modern Fertility app to log a picture of each strip and track your results over time. Modern Fertility currently recommends afternoon testing and says results should be read at five minutes.

How easy is it to use?
These strips are straightforward. As LH levels rise, the test line darkens, and the included chart helps you categorize your result as low, high or peak. Per the included chart, a light pink line is considered an LH value of 0 to 10 mIU/mL, medium pink is around 25 and peak fertility is the darkest line at 45 to 60 mIU/ML.

While it’s not required for use, Lindsay loved having the companion app to look back on her results. After each test, she took a picture of the test strip using the app and it automatically scanned and logged the result, allowing her to see her LH trends over time. You can also manually enter results if you wish.

It's worth mentioning that dim room lighting can affect how the app interprets the picture. Lindsay set up a space with reliable natural light for taking photos and found that consistency helpful when scanning her tests.

The Bump takeaway: The Femometer Ring Air is the Best of The Bump winner for best wearable for ovulation tracking. Its lightweight, comfortable design and clear cycle insights make it easy to continuously track your fertile window with minimal effort.

I’m not big on jewelry. Most days, I forget to wear my wedding band. But wearing the Femometer Ring Air 24/7 for almost a month was much easier than I thought it was going to be. It’s lightweight and comfortable, and the free sizing kit they provide makes choosing the right size for your finger as easy as can be. Even when sleeping, this ring was comfortable.

But the Femometer Ring Air isn’t just an attractive wearable. It provides continuous cycle tracking and detailed fertility insights, plus it logs your cycles individually so you can go back by date and see your period length, cycle length and ovulation day. It also compiles your cycles to provide statistics like your average cycle length, average period length, average length of luteal phase and average ovulation day.

Data collection
The Femometer Ring Air acts as a well-rounded health tracker. It tracks BBT, hot flashes, steps, active energy, heart rate, stress and sleep. You can also manually add things like your cervical mucus observations, mood and daily symptoms. What I especially loved about the symptom tracker was the detailed explanations as to why the symptom occurs and how to relieve it. Together, the cycle and health data gave me a detailed look at my patterns over time. I did find that its activity lagged behind my Garmin during testing, though, so I preferred the Ring Air primarily for its cycle and fertility insights.

Viewing your cycle is easy with both a chart view and a calendar view. The app tells you where you are in your cycle, when to expect your next period and how long your fertile window is expected to be. It also offers an estimated daily conception rate based on where you are in your cycle.

How it works
The Femometer Ring Air uses temperature, logged symptoms and cycle dates to predict your fertile window. There are two sensors on the inside of the ring that measure your temperature every minute throughout the night when you're sleeping. This is how it tracks your BBT and identifies temperature shifts associated with ovulation. When combining BBT with the manual data you input, such as the date of your last period and cervical mucus observations, the app can provide more context for its cycle predictions and insights.

How easy is it to use?
This ovulation tracker is as easy to use as slipping a ring on your finger! One thing to consider, though, is that the ring must be placed with the two sensors facing the palm-side of your finger. I found that a bit hard to track since the only way to confirm its position was to take the ring off and put it back on. Because of that, the temperature wasn’t always super accurate for me.

Once in the right place, the ring continuously monitors your heart rate and temperature without you noticing. And it’s sturdy enough to wear during workouts, diaper changes, gardening and showers. I put my ring through the punishing test known as daily motherhood, and it barely got a scratch.

The app is easy to navigate. Each category is clearly labeled and provides detailed information if there’s something you don’t understand. Inputting manual data is also easy to do. It only took me a few minutes to understand the app and the results it was giving me.

Another major advantage is how little maintenance it requires. The battery lasted about a week during testing and I could quickly recharge it during a meeting. There’s also no ongoing app subscription, so after purchasing the ring, I could access its fertility insights without another monthly subscription expense.

Overall, it’s a great low-effort way to track your cycle––with additional sleep, stress and activity insights for those who want a broader view of their health.

The Bump takeaway: The kegg Fertility Tracker is the Best of The Bump winner for best ovulation test for tracking cervical mucus changes. Its comfortable one-minute testing process and easy-to-read fertility ratings make cervical mucus tracking feel far more straightforward.

When you’re trying to conceive, it can be helpful to use more than one ovulation tracker at the same time—especially if you have an irregular cycle. Dr. Sekhon notes that tracking physical signs like cervical mucus alongside other fertility-tracking methods can be helpful, particularly when traditional LH tests are less reliable for your cycle or harder for you to interpret.

The kegg, which is inserted into the vagina to read cervical mucus, might sound intimidating to some, but it’s as easy to insert as a tampon. (I actually found it even more comfortable.) If you only want to take a simple fertility reading, it takes just 60 seconds—you can then easily pull it out thanks to the sturdy handle.

Data collection
The kegg checks electrolyte levels in your cervical mucus to track changes that might not be easily detected by sight or feel alone. And because judging cervical mucus on your own can feel subjective, kegg offers a quick, straightforward way to track subtle changes over time. The device connects wirelessly to an app on your phone and uses this information to produce a fertility report.

The results were easy to understand right away. After the 60-second test, a clear, bold result appears in the app indicating whether you’re at low, medium or high fertility. As the device gets to know your body, the fertile window predictions become more personalized. You can go into the app for more information, which you can view as either a chart or calendar depending on how you best like to receive information.

If there’s anything you don’t understand, you can jump over to the app's "learn" section for really clear explanations. My favorite part of the app was that I could toggle back and forth between my charts and the learn section without losing my spot on either page. This helped me comprehend the explanations even further, as I could see in real time what I was being taught about my own results.

I would recommend using the kegg alongside another tracker, especially for people with irregular cycles. While my results generally aligned with my cycle, I did receive one "medium fertility" result at a time when I knew my ovulation day was over.

Kegel exercises
An added bonus to the Kegg is its built-in kegel ball. You can choose to do a few kegel exercises before your cervical mucus test, which still only requires you to insert the kegg once per day. The app gives you a countdown on when to hold the kegel and when to release, and the ball vibrates alongside the countdown to clearly indicate what step you’re on. A lot of people question whether they’re doing kegels correctly, so I appreciated the guided feedback during each exercise.

How it works
Cervical mucus changes throughout your cycle, according to Cleveland Clinic. To identify your fertile window, Dr. Sekhon says you’ll be looking for “symptoms of impending ovulation such as watery cervical mucus which turns to egg white, thick mucus when ovulation has occurred.”

Rather than relying on the consistency of cervical mucus alone, kegg tracks subtle changes to electrolyte levels in cervical fluid to help identify your fertile window. It uses gentle electric pulses––which you don’t feel––to take a reading in just 60 seconds. When you’re done using it, simply wash it off with a mild soap. The device also reads your temperature, and combines this information with data you log in the app about the start dates of your period.

How easy is it to use?
The kegg Fertility Tracker is very user-friendly. You can’t use any lubricants to insert it, but you likely won’t need them. I inserted the kegg quickly and comfortably. And if it’s not inserted correctly, the app will tell you before starting your test.

Once connected to the app, you choose if you want to do kegel exercises before your cervical mucus test or just jump right into your test. If you don't want to take extra time for the kegel exercises, the cervical mucus test only takes 60 seconds to complete. You then pull out the kegg and get your results immediately.

Another great feature of the Kegg is that you can use it at a time that works for you, as long as you take your daily readings within the same consistent two-hour window. While other ovulation trackers require you to use them first thing in the morning, the Kegg allowed me to choose any two hour window of my day, giving me the freedom and flexibility in my schedule to use it when I knew a toddler wouldn’t be barging in on me in the bathroom!

While the Kegg comes in at a higher price point than other ovulation trackers, it’s a one-time expense. You don’t have to pay for additional wands or test strips, and when you’re finished with your fertility journey, you can continue using the kegg for kegel training.

The Bump takeaway: For precise BBT tracking without a complicated setup, check out the Easy@Home Digital Basal Thermometer, the Best of The Bump winner for best BBT thermometer. It measures temperature to the hundredth of a degree, with a bright backlit display and optional app for spotting patterns over time.

BBT tracking offers a simple, low-tech way to better understand your cycle by monitoring the subtle temperature rise that typically occurs after ovulation. The key is precision—since these shifts can be less than half a degree, a thermometer designed specifically for BBT tracking can make them easier to spot.

Data collection
After taking your temperature, you log it in the associated app, where you can also log information on past periods as well as any symptoms you’re experiencing and cervical mucus observations. These options can provide additional context about your cycle and what to expect during ovulation.

The app plots each temperature reading in chart form so there's a visual of how your temperature changes over time. This is used to spot patterns in your readings, which is especially helpful since BBT typically identifies temperature shifts after ovulation has occurred—you don't use it to spot an imminent fertile window, you use it to look at patterns over months, and figure out where your fertile window usually falls in your cycle.

I loved having the app as an option, but the interface was a bit cluttered and I felt some information overwhelm. The thermometer itself was the real standout of the set.

How it works
BBT testing works by taking your temperature when you’re fully at rest—that means before you get out of bed or even talk in the morning, you take your temperature. For accurate results, you need at least three hours of uninterrupted sleep. A sustained temperature rise over several days can indicate that ovulation has likely occurred. “Temperature shifts occur after ovulation, making it a retrospective rather than predictive indicator,” says Jenna Turocy, MD, a fertility expert at Columbia University Fertility Center.

Since BBT tracking identifies temperature changes after ovulation, pairing it with a method that predicts ovulation, such as an LH test, can provide a more complete picture of your fertile window. And Turocy says, “[BBT tracking] requires multiple cycles for pattern recognition.” So if this is your chosen method, stay consistent over several cycles to better understand your cycle.

How easy is it to use?
The Easy@Home thermometer has a flexible tip, making it comfortable to rest under your tongue. To use it, push the button, wait for the numbers to clear, then hold the thermometer under your tongue for 90 seconds. Once the reading is complete, the thermometer will beep and display the temperature with a blue backlit screen. I found it very easy to use, and it has a waterproof tip, so it’s easy to clean.

When using this thermometer, I was surprised at how long it took to get a temperature reading. You need to hold it under your tongue for 90 seconds––but the long wait time is by design. The thermometer measures to the hundredth of a degree, allowing it to pick up the subtle temperature changes used in BBT tracking, and it takes more time than the average thermometer to get a reading that precise.

I loved the bright, backlit display screen with bold lettering. It made reading my results super easy, especially before my eyes were ready to adjust to turning on the bedroom light. And for those of us who are memory-impaired, this thermometer offers both a built-in memory recall to store up to 30 previous temperatures as well as an app to store your results.
