I just ordered an FDA approved fetal doppler online today. It’s supposed to be here on the 30th- I’ll almost be 7wks by then. I know it’ll be too early to pick up the heartbeat. Just curious if anyone has used one before and how far long were you when you heard the heartbeat? I’ve read mixed reviews on the home use of them. I don’t plan on using it everyday day but given I’ve had to previous miscarriages, I just want a little piece of mind.
