Tips for using baby Doppler ?

Ma

Hi ladies ! I’m 11 weeks 3 days today .

I invested in a baby doppler , the cofoe brand .

I’m having issues finding the heart beat.

I’m also a plus sized girl

I’ve been trying to find it between my Pubic bone and belly button but no luck , I was able to find my own heartbeat rather easily .

Is there any tips for finding it ? I’m not worried or anything cause I do know it can be tricky , and isn’t something to be worried about if not found immediately… especially since I’m not a doctor lol
