Doppler can pick it up as early as 7 weeks but sometimes not till 10. Not sure about u/s
i had an ultrasound at 11 weeks and they wouldnt listen for it because they say sometimes they cant pick the heartbeat up and dont want to freak woman out , but you could see the heart beating .. my doctor wouldnt listen/check for it with the doppler until i was 14 weeks pregnant due to sometimes not being able to hear it .. they just dont want to freak people out i guess which i dont blame them. but ive heard some woman being able to hear it at like 8 weeks , maybe ask your doctor next appointment. every doctor and clinic/hospital is different i guess just depends on your doctor.
Here in UK we don't check for the heartbeat until around 15-17 weeks, in case we can't find it and it stresses the mother. However it is possible to find it from 9-12 weeks, depending on the woman's build and the quality of the doppler. On an ultrasound scan the heartbeat can be heard at around the same time it can be detected- 7 weeks. I heard my son's heartbeat via a scan at 7 and half weeks pregnant.
10 weeks :-)
