What's happening at 6 weeks
The heart starts to beat — though far too quiet to hear from outside.
What your baby is doing
A primitive heart tube is now beating around 100-120 BPM. Tiny arm and leg buds are forming.
What's happening to you
Nausea peaks for many. Cravings, aversions, exhaustion. You may have your first ultrasound this week.
On the heartbeat
Heartbeat exists, but only visible/audible via early transvaginal ultrasound. Far too quiet for any phone or doppler.
