I bought a doppler almost two weeks ago. I am 11 weeks1day. Wen we first heard a heartbeat we were sure it was buba. I recorded it and after counting the beats per minute i got worried that it was quite slow.(which i now know was mine). After a lot of research i filled my bladder and after an hour long hunt i found bubs! Defo this time. Around 120bpm soundin like a little choo choo. Does that sound about right?
