Congratulations, you're 21 weeks pregnant! Starting this week, your abdomen becomes big enough, so even strangers can tell that you are pregnant.

Along with the pride of carrying life inside of you, this week also brings some new and exciting changes for you.

More kicks from your baby.
As your baby’s bones harden, expect stronger kicks, pulls and rolls. Try to be attentive — you may even start noticing a pattern!

Belly button pops out.
Your inward belly button may now completely pop out of your abdomen, which is completely normal. As your uterus shrinks after delivery, it will go back inward.
