Weekly Highlights
- 1Baby’s Development. Your baby is considered early term (full term begins at 39 weeks). They're gaining about half an ounce a day, while the lungs, brain, and nervous system continue maturing. Most lanugo is gone, and your baby may already be head-down.
- 2Bodily Changes & Symptoms. Your cervix may begin to dilate, and you might notice the mucus plug pass. Common symptoms include pelvic pressure, back or hip pain, nausea, and trouble breathing until the baby drops. Contractions can be tricky to identify—Braxton Hicks are irregular and ease with movement, while true labor contractions are regular, intensify, and don’t stop.
- 3Health & Wellness. Group B strep screening usually takes place around now. Practice timing contractions, and call your provider for heavy bleeding, water breaking, or persistent, painful contractions. Watch for preeclampsia signs such as severe headache, swelling in the face or hands, or vision changes.
- 4Tips & To-Dos. Finalize your hospital bag, install a rear-facing car seat, and stock freezer meals. Review feeding plans, line up postpartum help, and finish nursery prep. Discuss baby’s position, visitor policies, and delivery expectations with your provider.

Checklist for week 37
- If you haven’t already done so, pack your hospital bag. The big day could be just around the corner!
- Stock your freezer with meals you can simply heat up. After your baby is born, you might not have time to cook.
- Finish setting up your baby’s nursery and get any baby essentials you haven’t bought yet at 37 weeks pregnant. Keep in mind that most babies don’t arrive exactly on their due date and that yours could come early.
- Consider getting a waterproof sheet to protect your mattress in case your water happens to break while you’re asleep.
- If you see breastfeeding or pumping in your future, make sure you have several quality nursing bras.
- Consider setting up a comfortable “feeding station” in your baby’s nursery or elsewhere in your home. For example, you might like to buy a comfy nursery glider, place a lamp or night light next to it, and have a nursing pillow and a quilt on hand to help you feel comfortable. Some parents also have a nursing basket nearby with supplies like tissues, burp cloths, nipple cream (if you’re planning to breastfeed), and snacks for you.

- If you have a little downtime this week, take a look at the best baby gear as selected and voted on by Pampers Parents. You might already have a lot of what you’ll need, but you may like to check out some feeding essentials (and nice-to-haves) like the best baby bottles.

37 Weeks Pregnant: Your Baby’s Development

Your Body at 37 Weeks Pregnant
At 37 weeks pregnant, your cervix may begin to dilate. When this starts to happen, you may lose the seal that protected your uterus from infection throughout your pregnancy. This seal is known as the mucus plug.
If, at 37 weeks pregnant, you notice some extra vaginal discharge that is clear, pinkish, or slightly bloody, this may be the mucus plug. Seeing this mucus discharge is an indication that labor is starting or is not far off. Keep in mind that you can lose the mucus plug hours, days, or even weeks before labor begins. Some pregnant people don’t notice it at all. Losing your mucus plug or having a little spotting isn't unusual around 37 weeks pregnant; however, if you notice severe bleeding now or at any time during your pregnancy, contact your healthcare provider. At 37 weeks, if you do notice the mucus plug on your underwear or on the toilet paper after you wipe, or if you are unsure if this means your labor has started, you may want to call your healthcare provider for advice on what to do next. Twins and triplets are more likely to be born earlier than a single baby, so keep an eye out for signs of labor if you’re 37 weeks pregnant with twins or more.
