So, I had unprotected sex with my boyfriend for the very first time on Sunday night. He didn't finish inside me. I've been on Cerazette for several years but we've always used condoms as well until now. Well, great timing because today I vomited around 3 hours after taking the pill. I decided to take another as a precaution, as the guidelines online seemed to vary between 2 and 4 hours being a concern after vomiting. Should I be OK? I'm not going to have unprotected sex again for at least 7 days, but I'm concerned about Sunday night.
