Doppler

Nicola • Married. 29 years old. Mmc at 11 weeks July 2015 and mc at 4+3 weeks Nov 2015. Pregnant with baby girl due 30.07.17 ♡♡

So I just used my doppler and I'm 8 weeks. I couldn't hear the heartbeat, only my own but at one point the heart rate on the doppler increased from 120ish to 172...could this have been baby's heartbeat??

I've had 2 mcs and 7 chemical pregnancies so I'm so worried xxx
