So I started my new pack of birth control pills for the month and I have forgotten to take the first four pills. Sunday through Wednesday. Then Saturday night I had unprotected sex multiple times back to back. But when he was about to cum he pulled out and I just swallowed. I'm scared that sperm could still have been on his penis when he put it back in. If I stop my birth control pills. What are my chances of being pregnant. Please help!
