Fetal Doppler help !

Emma

Help a sister out.

Trying to use a Doppler at 13+6 and not exactly sure where I should be looking?? I know the uterus is still low, and I feel like I hear it- but I’m not sure 😂😂

Any tips on finding heartbeat? Am I pointing it in the right place? Any do’s or donts? I’d appreciate any advice 😊
