I recently went on vacation and there as an hour time difference from where I live. I religiously take my pill at the same time everyday, give or take maybe 20 minutes once in a while. While on vacation sometimes it would be an hour later, but most of the time it was right on time. The day I got back from vacation I stayed with my boyfriend and we had sex 4 times in 12 hours (the pill was taken at the correct time that day), without condoms, and I just want to make sure that I don't need to take Plan B. I should be fine correct?
