My wife is 7 weeks and 3 days of pregnancy. Today we did a USG but did not get heart beat. We are in panic. Is it normal ? As doctor said may be it could be found in 8 weeks USG with TUV.

First unless you only had sex one time, conception dates are estimates, so there is no exact way to know for sure the week, and not the day of pregnancy. So she is about 7 week pregnant.

Many babies you can not hear the heart beat till about week 8 to 10, so the doctor said, MAYBE here (perhaps he said maybe) not you will hear it??
