What's happening at 39 weeks
Full term. Baby is officially done cooking.
What your baby is doing
Baby is shedding the last of the vernix and lanugo. Nails have grown past the fingertips. Skin is pink and smooth. They're just waiting.
What's happening to you
Every twinge feels like "is this it?" Sleep nearly impossible. Cervix may be dilating without you knowing.
On the heartbeat
Last full week of recordings, probably. Save them somewhere you won't lose them. You'll come back to these.
