Hi doctor, I had my period on 3 may. It lasted for 4-5 days. After that I had unprotected sex though he didn't release but to be safe, within half an hour after sex I took unwanted 72. After two days we again had sex. And then too I took unwanted 72. On 28 may I saw a bit of spotting. Or red and brown blood. It was very light. Like few drops. The spotting increased into a bleeding. But the flow is very less. It not at all like period. It happens mostly when I pee. The color of bleeding is deep red. It's been happening on and off. Now today is 31 may and there is no more spotting or blood. Am very much worried. Please tell me what it could be?
