Hi
My wife is having pain on her abdomin in her 8 week of pregnancy, according to her its too painful. What are tha causes and what should I do to control

I would call her OB/Gyn. Her own doctor should be diagnosing her issue not people over the Internet. Please give her doctor a telephone call.

I agree with TJ. We don't know your wife's medical history, how her pregnancy is going, and we can't examine her. This should be discussed with her doctor. You won't find any valid answers online.
