I'm on combined birth control for half a year now. I missed pill on 16th day of my cycle and skipped it for three consecutive days and on fourth day bleeding started. Now it's third day of bleeding. At the farmacy they advised me to skip 7 days and start a new 21 pill pack afterwards. I had unprotected sex during the days I skipped the pill. Could I get pregnant even if bleeding started? As it is too early to tell it with pregnancy test, can starting new pack of pills harm the baby if I got pregnant?
