I was using my fetal doppler i just rented its the same one the ob uses. i am about 16 weeks pregnant and i detected the heartbeat but it was jumping from 140-200! if i kept it in one spot it stayed at 143 so is it just the doppler? im trying not to worry but its my first baby and ive already had 2 miscarriges
