I bought a Doppler and its pry been used several times before I got it. I haven't heard heart beat yet or seen my baby. I found out on my birthday the 27th and went in to the clinic and said I was 7 weeks with just estimating from my period. I'm nervous, I try not to think about it but it's hardy. I used the Doppler Friday with girly color lotioned them couldn't hear anything then on Saturday I just didn't use anything and there were numbers it ranges from 41-191 lol, so idk what that was about but didn't hear anything at all, then I used that sunburn gel and still couldn't hear anything. Idk if I broke it by using that lotion. But am I doing it wrong or should I be worried or did I break it.
