Key Takeaways at 11 Weeks Pregnant

  • Between now and week 14, you’ll have the first trimester screen; this consists of a nuchal translucency screening (NTS) via ultrasound (this looks at the thickness of the back of baby's neck) and a blood test. Together, the results can determine baby’s risk for certain chromosomal abnormalities or conditions.
  • You may have a teeny baby bump at this point—or your clothes might start feeling a bit tight. Either way, you won’t be able to get away with your regular jeans for much longer.
  • You’re in the thick of the first trimester and those pregnancy symptoms are still strong, thanks to all that hCG flooding through your system. Sore breasts, morning sickness and out-of-control exhaustion are just a few things you might be experiencing. Rest assured that these unpleasantries should improve in a few short weeks as you approach the second trimester.

Pregnancy week 11 is a great time to start planning a babymoon with your partner. We recommend you go on this trip in the second trimester, since that’s when you’ll feel most energized, and we doubt you’ll want to do a lot of traveling once you hit the third trimester. So at 11 weeks pregnant, take your mind off your queasiness and start scouting some destinations now. (Staycations totally count!) If you need another diversion, imagine your growing baby at 11 weeks, doing just fine in there, becoming more developed every day.

Baby at Week 11

You can't see it, but baby is moving fluidly and gracefully inside your 11 weeks pregnant belly. Your 11-week fetus has skin that’s see-through but is on its way to becoming more opaque. At 11 weeks, baby's fingers and toes aren't webbed anymore. Their face is taking shape too, and tooth buds, hair follicles and nail beds are forming. Plus, they can open and close their mouth. Cool, huh?!

Equally exciting? Baby’s brain is developing both left and right hemispheres. The left side is responsible for logic, while the right will help baby process language.

You might not know baby’s sex for a few more weeks. But their external genitalia are starting to form into female parts (a labia majora and clitoris) or male parts (a penis). And perhaps most exciting: when your doctor uses a Doppler stethoscope, they’ll be able to hear the heartbeat.

How big is baby at 11 weeks?

Baby is now as big as a lime! Your 11-week fetus is between 2 and 2.5 inches long and weighs in from .33 to .5 ounces. They’ve got about a 1:1 head-to-body ratio. (It may sound weird, but that will change!)

11 weeks pregnant is how many months?

Pregnancy lasts 40 weeks, so doctors tend to track your progress by weeks, not months. But if you really want to know, at 11 weeks you're about two months and three weeks pregnant. In three more weeks, you’ll begin the second trimester.

11 week ultrasound

Right around now—between weeks 11 and 14—you may be getting a first trimester screen. This is a combo of a special ultrasound called a Nuchal Translucency Screening (NTS) and a blood test. During the 11 weeks pregnant ultrasound, the technician or doctor will measure the back of baby’s neck. An abnormal measurement could be a sign of a chromosomal abnormality. Then the blood test will screen for too-low or too-high hormone levels. Taking into account the results of both the NTS and the blood test, your doctor will tell you baby’s risk of having certain chromosomal conditions. Waiting for the results may be nerve-wracking, but knowing the results will likely give you peace of mind.

For women who are 11 weeks pregnant with twins, an ultrasound at this point would show the babies’ umbilical cords and either one placenta or two. If the babies share a placenta, the fetuses are probably identical twins. If they have two separate placentas, they may be identical or fraternal. Identical twins sharing the same placenta usually need more frequent check-ups to be sure they’re both getting enough nutrition. Yep, even in utero these siblings already have to learn to share!

Pregnancy Symptoms at Week 11

Around 11 weeks, your body (and mind!) are still completely haywire. It’s probably tough to feel calm right now, since your hormones are still raging and you may still be feeling pretty nauseous. But know there’s light at the end of the tunnel—just a few more weeks left in the first trimester, which is notoriously the worst for pregnancy symptoms! Here’s more about what you’re likely feeling at 11 weeks pregnant:

Fatigue

You’re beat, but you can expect a surge in your energy in trimester two. Until then, give yourself permission to kick back and get some extra rest.

Nausea

We get it. You’re sick and tired of being sick and tired. We promise you should start to feel more like yourself soon.

Gas

Sorry, but tummy troubles are par for the pregnancy course. If you’re experiencing uncomfortable rumblings and bubblings, keep a close eye on your diet (if you’re able to hold anything down, that is) and try to avoid foods that make you gassy, such as beans, cabbage, fried foods and desserts. Drink lots of liquids and eat fiber-rich foods too.

Mood swings

Are you feeling up one minute, then down the next? Mood swings are completely natural thanks to the hormones swirling through your body. Try some mind/body exercises, like yoga, to help you feel more Zen. And if possible, avoid stressful situations. If the mood swings seem drastic, or you have a history of mental health issues such as depression or anxiety, it helps to check in with your doctor.

Leg cramps

Tight, painful muscles can strike at night and interfere with your sleep. Drinking plenty of water can prevent leg cramps, and so can stretching your legs during the day. You also want to take a look at your diet to be sure you’re getting enough potassium and magnesium.

Skin darkening

One morning you might wake and think, “whoa! What’s that dark line down the center of my belly and why is it there?” Well, this is a totally normal pregnancy symptom called the linea nigra. This dark line is caused by hormonal changes and isn’t usually permanent, though you might notice that it sticks around for a while after you give birth, especially if you breastfeed (because of the hormones involved with nursing).

Vaginal discharge

Okay, so you’re probably going to want to invest in some pantiliners, because an increase in discharge can be expected throughout your pregnancy. This 11 weeks pregnant symptom is your body’s way of eliminating secretions from the vagina and cervix.

Women who are 11 weeks pregnant with twins often have elevated hormone levels, which may mean double the symptoms and higher weight gain. Both are normal, and you’ll likely experience increased energy and decreased nausea in the coming weeks.

What you might feel like at 11 weeks pregnant

Wondering what you should feel like at 11 weeks pregnant? You’ve probably got some of those 11 week pregnant symptoms we mentioned, as well as general aches and pains as your body is undergoing so many changes. On the plus side, you may be noticing that your hair and nails are starting to grow. Above all, continue to listen to your body and rest when you need to.

Your Pregnant Belly at 11 Weeks

Is that a baby bump or gas and bloating? At 11 weeks pregnant, it can be hard to tell! Especially if it’s your first pregnancy, you might not be showing at 11 weeks. Women pregnant with their second babies and those who are 11 weeks pregnant with twins tend to start showing earlier than first-time moms-to-be.

While your belly may or may not be visibly changing, you may be surprised to see your breasts have noticeably changed (which may be welcome or unwelcome, depending on your preference!). We recommend you shop for some new, comfy, stretchy bras at this stage in the game. If you’re planning on breastfeeding, a nursing bra can be worn now and will come in handy after baby’s born. Plus, nursing bras are normally made to keep up with a changing bust size, and you probably have some more growing to do.

With an 11-week fetus, the chance of miscarriage might be on your mind. It’s tough not to worry—welcome to motherhood!—but now that you’ve seen baby’s heartbeat, your miscarriage risk has significantly dropped, and once you hit your second trimester, the risk will be less than 1 percent.

Can I have a baby bump at 11 weeks pregnant?

Definitely! Every woman’s body is different, and a bump can start popping out when baby’s at 11 weeks (especially if you’re carrying multiples or have been pregnant before). In some cases, the first sign of a bump may not be a rounded belly but a too-tight feeling in the waistband of your favorite jeans or skirt. Time to shop for maternity clothes!

Can you feel baby move at 11 weeks?

Was that a kick you just felt? You’re probably eager to experience those magical first flutters and wondering, “can you feel baby move at 11 weeks?” At this stage, it’s probably a little too early to feel baby move—that won’t “kick” in until around the second trimester. That’s because your 11-week fetus is still too small, but don’t worry—it will happen soon!

Tips for 11 Weeks Pregnant

Want to take charge of your health and that of your future baby? Here’s what you can do now.

Get lots of calcium

Helping baby grow strong bones and teeth requires about 1,000 milligrams of calcium as part of your daily diet. Dairy products like milk, yogurt and pasteurized cheese are always good choices, but you can also get calcium from other sources like almonds, salmon, tofu and eggs.

Take a walk

Stretch those legs! Walking is one of the best forms of exercise during pregnancy because it’s safe, easy to do, gentle on the joints and a great all-over workout. If you’re new to exercise, walking is also ideal because you can start at your own pace and distance and work up gradually. Plus, all that fresh air and movement may help with nausea! Just make sure to drink plenty of water and avoid walking during the hottest times of the day.

Eat right to avoid heartburn

Gas and nausea during pregnancy are hard enough without throwing heartburn into the mix. You can curb that acid reflux by eating small meals and steering clear of foods that are heavy on spice and fat. And as great as it feels to put your feet up after a meal, try not to lie down right away so your food can properly digest.

Baby your skin

When baby’s at 11 weeks, your skin hasn’t started to expand too much yet, which is why it’s the perfect time to be proactive about stretch marks. There’s no sure-fire way to avoid those stripes (sometimes it’s just a matter of genetics), but moisturizing regularly, drinking plenty of water and eating skin-boosting nutrients like Vitamins C, E, B2, B3 and zinc can help.

Frequently Asked Questions

Can I take ibuprofen during pregnancy?

Your safest bet is to avoid this pain- and fever-relieving medication while you’re expecting. Studies suggest it might carry some risks during pregnancy, especially after week 20. That said, in the first trimester, its use could possibly increase the chances of miscarriage and a condition called gastroschisis (where the intestines stick out of a hole in the stomach wall). After week 20, the US Food and Drug Administration (FDA) recommends avoiding ibuprofen unless your doctor feels it’s necessary. Among the potential risks, it could lead to serious complications, like poor lung development and high blood pressure in the fetus, and even preterm delivery. For a personalized answer, check with your healthcare provider, who will likely recommend acetaminophen (Tylenol) instead.

What are some natural ways to destress and relax during pregnancy?

Self-care will benefit you and baby. Along with getting plenty of rest, try to fit in some moderate exercise, like long walks. Listen to soothing music, read, spend time with a close friend and explore mind-body techniques, like yoga, meditation, and prenatal massage (the latter can also help with back pain). Before booking an appointment for bodywork, though, check in with your healthcare provider.

What foods are best for fetal development at this stage?

Good nutrition is important throughout your entire pregnancy. Each day, aim for at least four servings of dairy, three servings of protein, six to 11 servings of grains, two to four servings of fruit and four or more servings of vegetables. By sticking to a balanced diet, you’ll take in nutrients that will nourish baby. For instance, iodine (in dairy and baked potatoes) will help support the development of their nervous system and folate (in dark green leafy veggies and legumes) will help prevent neural tube defects like spina bifida. Ask your doctor whether you should take a prenatal vitamin and folic acid supplement.

Why am I experiencing so much nasal congestion?

If your nose is stuffy, your pregnancy hormones might be the culprit. They sometimes dry out the lining of the nose, causing it to become swollen and inflamed. For relief, try placing a warm wet washcloth on your cheeks, eyes and nose. Drink more fluids, use a humidifier or vaporizer, and take a warm shower or bath (bonus: the latter is also a wonderful stress reliever).

How much water should I drink during pregnancy?

Now that you’re a mere three weeks from your second trimester, prepare to up your daily water consumption beyond the eight to 12 cups you’re already drinking. Starting in week 14, the goal will be an extra one to two cups per day.

I couldn't look at chicken for a solid two months. I didn't experience intense cravings, but the aversions were awful. I sustained on buttered noodles and bagels for the entire first trimester.
