I've been having unprotected sex for months. My cycle is always irregular. I didn't see her at all in the month of January. I took two pregnancy tests all negative! No symptoms of pregnancy. February 2, 2015,hello mother nature, which lasted 7 days. March 4, 2015 I see her again and it's her normal heavy flow. Yesterday I went to the bathroom to urinate & I notice a fleshy blood clot escape me. Can anybody tell me what's wrong? I also have pictures.
