My wife is 4 month pregnant. She is having pain in lower abdomen. We consulted one gynac,and after sonography doctor said that her cervical distance is 2.9 cm & she have to take stiches so that baby does not come down. Then we consulted other gynac, where doctor said there no need to take stiches so early in 4th month. She is having pain day and night. Please suggest me what should i do ??
