So I bought a fetal heart doppler today. I'm 15 weeks today and tried it but couldn't find a heartbeat which doesn't worry me because the doctor couldn't find one last time I have too much scar tissue from my 2 csections. So we had to do and ultrasound and everything was fine. I go to the doctor's Wednesday and I'm sure everything is fine.
