18 Weeks Pregnant How Big is My Baby

Eighteen weeks into your pregnancy, you've nearly reached the halfway mark-- and your baby is just one month away from viability! Although you've probably got a nice bump and you're likely feeling some kicks and flutters, it may still be difficult to imagine what your baby looks like and how big she is.

The Baby's Exact Size

Good luck with the rest of your pregnancy!
