I can't help but use my doppler everyday! Does anyone use there's everyday?? I find the heart beat so fast I use it for like less then 60secs. I told my hub he needs to hide it from me. Ive lost 2 babys in the past thats why I check once a day. I wanna start using it once a week. I couldnt find anything saying it was harmful to use it everyday. What do you think??
