Paranoid for no reason 🙄

I've been on the pill for the past two years and religiously take it. This month the latest I've been was a little under two hours.. my boyfriend always pulls out as well. But when my placebo period week rolls around, I always get so nervous! Like right now, I feel totally fine. No weird symptoms or anything that would indicate pregnancy at all... my period doesn't even start till the 3rd or 4th placebo day either. Yet I just get so concerned! Anybody else weird like this?
