21 weeks (almost 22)...

"Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long — the length of a carrot. If you're having a girl, her vagina is formed now, though it will continue to develop until birth. Your baby is really on the move now. Fetal researchers say babies move about 50 times an hour even while sleeping. All that movement helps stimulate your baby's physical and mental development. You may not notice 50 kicks, punches, and twirls during the day, but as you're settling down at night, don't be surprised if your little guy seems ready to dance the night away.
