Pregnancy Weeks 37 & 38
Your baby could arrive at any time–and it would not be considered 'early.' Your baby is now 'full-term,' which means he or she is likely to be big and mature enough to survive in the outside world. However, you may still have to wait a few weeks.
Your Pregnancy Week 37
What is happening with your baby at pregnancy week 37?1,2
- Your pregnancy is considered full-term when it reaches 37 weeks. Your baby is almost ready to be delivered, and you'll meet them in the coming weeks.

- It could contain bits of lanugo (fine hair) that were covering your baby earlier in pregnancy.
How big is your baby?
Your baby is approximately the length of 2 cucumbers and the weight of 14 baked potatoes.3
- If this is your first pregnancy, your baby moves down at 37 weeks and is ready to be born. When this happens, you may feel more at ease, and you'll probably notice increased pressure in your lower abdomen.

- It's common to experience some leakage from your nipples.
