Fetal Doppler

Aryn
So at what I though was 10 weeks my np used a fetal Doppler and imeadiatly picked up a very loud and strong heartbeat. She said she thinks I might be further along than we thought. I still haven't had an ultrasound and was wondering if anyone else had a super strong heartbeat on a Doppler before. Also has anyone had a miscarriage after hearing a heartbeat that strong after 10 weeks. I'm now about 11 weeks or at least that's what I think lol
