Hi Dr., I am 31 years of age, i had my period on the 10th and it ended on the 14th of this month. on the 16th, I had unprotected sex and took an emergency pill since i didn't want to get pregnant. I notices i was having some pain in my lower abdomen, like menstrual pain and breast tenderness on the 22nd, later on, I started bleeding even till now. the blood looks brown and the flow is light. Please what is happening to me?
