I just had a baby 2 months ago & my boyfriend & I have been having unprotected sex since before the 6 weeks was up & now 2 months later I started bleeding again, I'm currently on the Depo shot. I get pains but it doesn't feel like cramps & my cervix is really sore, I heard about girls getting cervical cancer & I'm worried... I don't think my cervix & stomach should feel the way they do. Please help!
