Hello, Im 16 years old. Just Had A Baby 2 Months Ago by emergency c-section. I Know i should have waited to have sex but, I didn't. I took a pregnancy test around April 16th and it was negative. I had sex around the 27th right after my period. My period is late this month, by 6 days then I began to see light pink to medium red blood most of the time only when I wipe. Sometimes it was brown too. I've also passed clots. Not enough blood to fill a pad, and occasionally can fill a toilet. What could be wrong? Could I be pregnant again or am I starting my period?
