Pregnancy - Week 39

By Tempdrop team

At 39 weeks, your baby is the size of a pumpkin. They grow a bit more to the size of a watermelon by 40 weeks. Since your baby is now full term, they won’t grow much more until after they’re born.

Your baby is considered full-term at 39 weeks! Your baby could come at any time. It may surprise you a bit, but your baby will likely move a bit less once they hit full term. This is because they are getting big, and don’t have as much space to move around.
