Had a doctor's appointment last week and the doctor could not find the heartbeat. The next day, the doppler I ordered from Ebay arrived *HI-bebe doppler*.
I tried twice but couldn't find the heartbeat. For now, I've put it away until next week.
Often times, 12 weeks is really early to detect the heartbeat.
Don't stress about it, put it away for a week and try again
The good thing is, your doctor found it
BTW, I went back in my pregnancy journals of my first two pregnancies. The doctor detected the heartbeats at 13 weeks but they were very faint. By 17 weeks, they were beating strong
