How big is your baby at 17 weeks? Spread one of your hands wide open—your baby is about the same size.
By 18 weeks, it might look like your baby is bulking up! Over the last week, her weight has increased about 50 percent.
Believe it or not, 20 weeks heralds the midpoint of your pregnancy. If you go full term, your pregnancy will be about 40 weeks long. You're halfway there!
If you were able to see a picture of your baby around week 9, you might have thought he was "top heavy" because his head was so big. Not at week 21.
By 22 weeks, your waistline may have vanished, but you can probably still bend over easily, sit comfortably and walk without effort.
