So I've been on Birth control for 3-4years now and right now I'm in a relationship and we've had sex and during that time I was taking my birth control consistently. we've had sex and now my period is late about a week late, I don't know rather to Take a pregnancy test or too just wait ?? I'm confused a little worried but I don't know what to do.
