Decisions, decisions. Now that you’re 17 weeks pregnant, start making firm plans, like whether or not you’re going to find out baby’s gender (you should be able to soon!), and what kind of childbirth class you’d like to take. As you start making these decisions, the pregnancy will feel even more real, which is super exciting, but part of you is probably feeling a little anxious too. After all, you’re at week 17 of your pregnancy; that’s almost halfway through and there’s so much to do, it can be overwhelming. Our best advice? Don’t try to do it all yourself—ask for help. And whatever doesn’t get done? You’ll find it’s not that important anyhow.
How Big Is Baby at 17 Weeks?
A baby at pregnancy week 17 is the size of a pomegranate. Your 17-week fetus is about 5.1 inches long and weighs about 5.9 ounces.
17 Weeks Pregnant Is How Many Months?
At 17 weeks pregnant, you’re three months and about three weeks pregnant. By the end of the week, you’ll officially be four months pregnant. Woot!
When you’re 17 weeks pregnant, symptoms are most commonly due to your rapidly growing baby. Here’s what you’re likely feeling this week:
Baby’s working on getting stronger, and your 17 weeks pregnant body’s working on getting bigger—about one to two pounds bigger per week. (Weight gain should be about the same if you’re 17 weeks pregnant with twins.) Make sure you document your growing 17 weeks pregnant belly by taking lots of photos. We promise: one day you’re going to look back and reminisce about this time. You’ll want to have a keepsake of how your body changed.
Baby's rubbery cartilage is now turning to bone. And baby's growing some meat on those bones, putting on some fat. Your 17-week fetus is growing a stronger, thicker umbilical cord too.
You may have a 17 weeks pregnant ultrasound if you’ve opted to have a cordocentesis. In this procedure, umbilical cord blood is tested for signs of chromosomal abnormalities. The doctor uses an ultrasound to find the place where the cord meets the placenta—that’s the spot where she needs to remove the blood. Typically, this diagnostic test is performed after 17 weeks; it may be used if amniocentesis results were inconclusive and you and your partner want a more definitive answer about baby’s health.
