I’ve bought a home Doppler and really regret it!
I used it a few times yesterday and picked my own heartbeat up then after ages of using it heard what I thought was a background heartbeat for about a second. Couldn’t find it again. Used it this morning and still can only hear my own. It’s not causing me worry, feel stupid for getting it! I’m about 15 weeks anyone else who couldn’t pick it up and everything was fine? Is it normal not to hear it?
