My girlfriend started birth control on the fifth day of her period. We had unprotected sex four days after she had been on the pill, so, maybe two days after the end of her period. Then we had unprotected sex a few more days over the next couple of days. Each time i did not ejaculate inside of her, if ejaculated at all. Is there a good chance she can be pregnant from this? Any advice at all will help. thank you!
