A 27-year-old female asked:

Can a doctor mistake baby's heartbeat with mom's when using a fetal doppler? or does that normally not happen. i am 14 weeks & it a took a minute to find my baby's heart rate which was 140bpm?

I wouldn't assume so. The pregnant mothers heartbeat would be expected to be in the 70-110 range depending on activity, The fetal heart beat range would be ~130-150. The fetus is often un cooperative when you want them to be still for a study so taking a while to find it is not unexpected.

The fetal(baby's) heart rate is normally much faster than an adult's as it is here. The confusion if any can be usually resolved by feeling the mothers pulse rate while listening to the baby's heart. Good luck.
