Question!

Caroline • Journey to conceive baby #1!
Kind of TMI, but my SO and I were having sex earlier. He was on top. I guess he went too hard because now I'm feeling strange pain near my lants waist band. Right where my uterus is. It hurts to sit and laugh and cough. We've had hard sex before and this has not happened. Should I be worried? I'm just kind of confused. Thanks ladies :)
