Last Saturday which was the 21 of April my bf and I had unprotected sex and it was my last day being on my period so I wasn't really bleeding. Then the next day which was Sunday April 22 I started my pill packet again. I've been on birth control for about 3 years now and started a new birth control called Junel Fe back in the beginning of November. I'm pretty good at taking at the right time. I usually take it at 9:35pm, but this time I forgot and went to bed early and woke up and then took it at 1:00am on accident. My bf thinks that he might have came in me a little, but he says that I should be fine since I've been on birth control for so long and that he did pull out before completely coming inside of me. I'm afraid that since I forgot to take my birth control 4 and a half hours late that I could be at risk of being pregnant. Should I be worried and when should I take a pregnancy to make sure if I am or not?
