I just had my baby girl in August, she's only about to be six months. I've been having really abnormal cramping, it's like pulsating, the past two weeks it's started to be extremely sensitive and painful when I have sex. I couldn't understand why it never hurt before and now it does if I had sex too early after her. My doctor wasn't really trying to give me answers to my pain, but he asked if I could be pregnant I took a test earlier that week and it was negative... Now I'm just trying to figure out what could go wrong or I guess really what other women have gone through complications getting pregnant agin so soon?
