I had unprotected sex 26 days ago using the withdrawal method. My period then came on its normal day and lasted 4 days as it usually does! I have not been sexually active since that time and now 10 days after my period I am bleeding, I wouldn't call it spotting cause it is continuous bleeding but very light. I went on the pill after my normal period and missed a few pills and just gave up and stopped taking the pills. Could this be the reason for me bleeding? Please help me?
