How Big Is Your Baby at 39 Weeks?

Your baby is 19.9 inches long and weighs 7.3 pounds this week. That’s about the size of a Cabbage Patch Kid doll.

Here’s what else to know when you’re 39 weeks pregnant:

Your Baby’s Development at 39 Weeks

Congrats, baby, you’re officially full term! Your baby is getting ready to make its debut any day now. Here’s what’s happening with them at 39 weeks.

  • Full term: Your baby’s officially considered “old enough” for delivery. Even though you may be ready for baby to be born, this week they’re still putting down fat deposits, and their brain keeps developing to get them ready for the wild stimulation of the world.
  • Milder baby movements: Your baby isn’t kicking and moving around as wildly when you’re 39 weeks pregnancy because it’s tight quarters in there. Even if they’re not as sharp, your baby’s movements should be just as often as usual. If you have trouble getting your baby to move, try drinking some cold water to wake them up; if that doesn’t work or you have any concerns, call your healthcare provider to check in. They may want to monitor baby’s movements with a nonstress test.
  • Skin cell turnover: Your baby is forming new skin cells to replace the older ones. The new cells will help with temperature regulation after birth.

💛 Congratulations 💛

One more week till your due date. You are full term!

Top Tip for 39 Weeks Pregnant

Nipple stimulation does help bring on labor. It’s so effective that you should probably avoid it if you’re not at a hospital or birth center (or if you have a high-risk pregnancy).

Your Body: 39 Weeks Pregnant Symptoms

You are this.close to meeting your baby! Your body is gearing up for labor, and you may be experiencing Braxton Hicks contractions or find out that you’re dilated. Here are some of things you may be experiencing when you’re 39 weeks pregnant.

  • Lightning crotch: This phenomenon is almost as exciting as it sounds. It’s a short, shooting pain in your pelvis that can get triggered when you or your baby moves. It hurts because your baby’s head is putting pressure on your cervix, where you have a ton of nerves. Most of the time it’s just uncomfortable and goes away quickly. For relief, you might get into a pool, which will lighten the load on your pelvis.
  • Braxton Hicks contractions: These practice contractions may still be happening, and they may be getting a bit uncomfortable. Take note of the tightening—when it starts getting regular and undeniable, it’s no longer Braxton Hicks; it’s the real deal!
  • Dilation and effacement: At your appointment, your OB or midwife will probably do a cervical exam to see if you are starting to dilate or efface. This is what happens: they put a couple fingers into your vagina to determine if your cervix is opening. This can help determine if the labor process is starting, but it can’t accurately predict when you’re going to deliver. Some women have early labor that they don’t even feel as their bodies ramp up for childbirth, and others stay at 0 centimeters until after their water breaks.
  • Vaginal discharge: It’s normal to have an increase in discharge when you’re 39 weeks pregnant. But don’t mistake leaking amniotic fluid for discharge. Amniotic fluid is thinner and waterier—seek medical guidance right away if you notice it or if you’re unsure of what you’re experiencing. Amniotic fluid can be mistaken for leaking pee too.

Fun Fact

Human pregnancies last about 268 days from ovulation, putting us between cows at 286 and chimpanzees at 240. Elephants are pregnant for 645 days, or almost two years!

Your Life at 39 Weeks Pregnant

Your due date is mere days away. Is the anticipation killing you? Here are some things to consider as you wait for contractions to start.

  • Top tip: It’s okay to ask for help if you need it, even before your baby arrives. The last few weeks of pregnancy can be a blur of sleepless nights, back aches and nesting, and an extra hand can give you time to nap or put up your feet. Take advantage of the fact that no one can resist helping a waddling, about-to-burst pregnant person.
  • R&R: And while we’re on the topic of putting your feet up, please relax as much as you can! Your mind may be working on overdrive, but your body deserves some rest. Do what you need to do to chill out for a while. (Here’s a birth visualization meditation if that’s your thing. Remember to sit or lie on your side.)
  • Get physical: In most cases, sex is safe straight up until labor begins (as long as your water hasn’t broken). Plus, having sex in the last week or two may actually help to induce labor. The theory goes that orgasms can cause contractions. So, if the mood should strike, don’t hold back.
  • Good to know: If they haven’t already, your OB or midwife may soon offer to perform a membrane sweep. During a vaginal exam, your practitioner swipes their finger around your cervix to separate the amniotic sac from the uterus. Studies show that a membrane sweep may reduce the need for a medical induction. It’s safe, quick and can be performed more than once, although it’s not the most comfortable feeling in the world.

Your 39 Weeks Pregnant Belly

Remember how you used to be so nervous about delivery? By the time you get to 39 weeks pregnant, you’re probably more than ready for your baby to be born. After all, your baby is around 20 inches long, you’ve probably gained a total of around 25 to 35 pounds and you’re more than a little uncomfortable—not to mention really eager to meet your little one!

Rest assured your baby will arrive when they’re ready. As you wait it out, try to take advantage of the time you have left by relaxing and maybe getting a pedicure or some other self-care.

  • Try to relax and get some rest before delivery.
  • Ask your healthcare provider or midwife if a membrane sweep might be right for you if you go past your due date.
