I need help everyone. A few days ago onthe 22 of October I had a very light bleeding that lasted only a day and a half. I am usually a very heavy bleeder and last about five days. Also this occured about a week before my period is due. I am on birth control and my boyfriend and I use condoms. We start having sex without one and then when he is nearing the end he puts one on. He has not ejaculated inside of me. Is there any way thnat could have been implantation bleeding? If so when can I test?
