How many mommies have an anterior placenta? I'm pretty convinced I have 1😔 I'm almost 16 weeks it's still hard to find my baby heart beat on the Doppler, this is my 2nd pregnancy and have barley felt flutters, and I realized today it was easier for me to find the heartbeat on the Doppler standing up rather than the normal laying down😑 I don't have my anatomy scan for another couple weeks😁
