After loss it's like I've constantly been on edge with this pregnancy so I ordered a fetal doppler from Wal-Mart it came in today 2-3 weeks earlier than it was supposed to. Usually you can't hear a heartbeat with a doppler till between 10 &14 weeks this particular Doppler said 16 weeks but I am 8 weeks 1 day and heard my baby's heartbeat at home! The heart rate was a beautiful 142! Seriously the BEST $35 i have EVER spent! Really helped to ease my mind.
