Hello, this morning I had unprotected sex with my sigificant other of a year and a half. After intercourse it was like I had started my period, and theres a slight feeling on the inside of my belly button. When I cough it is like a sharp pulling feeling. During intercourse I could feel a sharp pain on the in stroke almost everytime? Months previously today it had happened once before, only alot sharper and more painful. Ive recently had a C-section with my first child and, I have recieved a dose of the depo privera I was supposed to receive a second on march 23rd but never attended the appointment
