I have been on birth control for about a year now and I have taken it regularly. But I finished my last pack of pills and had my period like normal. I wasn't able to get my refill so I went a week with out Birth Control. I had sex, but had the morning after immediately and then realised a started bleeding the next day. I got a new pack of pills and started taking them again and the bleeding stopped. But now i have only been taking this new pack for a week and I have started my period. I also had sex last night before my period had started. Is something wrong? Could I still get pregnant?
