I didn’t hear mine until 10 weeks

I didn’t until my 12 weeks appointment.

You can see it beating on ultrasound earlier than you can hear it

my doctor didnt let me hear my baby's heartbeat til 14 weeks, i got a baby doppler online and ive been able to hear it myself since i was 8 weeks 4 days.

On ultrasound, yes. My doctor started using the Doppler to listen to my baby’s HB starting at 12 weeks

I heard my babies at 7 weeks but don’t be alarmed if your don’t hear yours at 8 weeks everybody’s different and it’s common to not hear the heartbeat until later.
