My Ex girl friend has been taking birth control since she was 16. She is now 22 any ways she ran out of BC pills and stopped taking them two months ago she missed her period and had gone to the doctor to get a pregnancy test. That came up negative and was not starting here period so the doc gave her some pills to make her start. Well she started her period last week and it has passed. We had sex twice since then and I came inside her twice. Is there a good chance she is gonna get knocked up? Is a girl most fertile after a period?
