I have a copper coil, this month I experience early brown discharge for 2 days. It started again after I had sex with hubby. Last Sunday I had cramps and all of the sudden, a dark small clots and blood. It only came off for 2 hrs. Went to the doctors, she checked saying that the copper is in place. I feel tired, my breast are not swollen but my stomach is bloated and my belly button is out. What could that be?
