Everyone's experience with fetal dopplers
OK guys. I'm about 11.5 weeks along, and I just broke down and rented a fetal doppler from online, just for peace of mind. Anyway, this particular brand advertises you can hear the heartbeat as early as 10 weeks. I was listening to the instruction CD that came with it with the different sounds and afterwards, noticed, I cant hear my baby's heartbeat. The only thing I'm hearing is swooshing sounds of fetal blood flow. Needless to say, instead of giving me peace of mind, it hasn't.
Those of you with experience with these, how early in the pg were you able to hear the actual heartbeat??
