What's happening at 33 weeks
Baby's immune system is getting a boost — antibodies passing from you to them.
What your baby is doing
Baby may be settling into a head-down position, though many still flip. Their skull bones aren't fused yet — they need to overlap to fit through the birth canal.
What's happening to you
Braxton-Hicks more frequent. Pelvic pressure intense. You may be noticeably waddling now — and that's fine.
On the heartbeat
Heartbeat is unmistakable. A good week to play music near the bump and record baby's response — many show shifts in heart rate and movement.
