What's happening at 21 weeks
Baby's movements are no longer subtle. You'll be sure now.
What your baby is doing
Eyebrows and eyelids are fully formed. The digestive system is practicing absorbing sugars from the amniotic fluid. They have their own sleep-wake cycle that's not yours.
What's happening to you
Stretch marks may appear on belly, hips, breasts. Heartburn ramping. You may feel surprisingly hungry between meals.
On the heartbeat
Capture sessions are smoother — heartbeat is louder and baby is bigger. Save a recording this week even if you have others. Voices change quickly.
