My girlfriend and I had sex and part was protected and part wasn't. I never ejaculated in her but we were worried so she took plan B 48 hours later. Also the day before she started birth control. Should I still be worried?
Birth control pills do not start being active until the second week of your girlfriend taking them. There is a chance your precum could have contained actual semen, but that would only be if you had ejaculated the fay before and not peed since then. If you didn't come inside of her then it shouldn't be bad :3
