My boyfriend and I took a bath together and then after that we took a shower together and while in the shower we rubbed genitals for a little while, he didn't go inside of me or anything but he did rub my vagina opening. I've been using oral contraceptives and have been taking it at the exact same time every day maybe ten or fifteen minutes late the entire 21 days. What I'm kind of worried about I'd if there's any chance I could be pregnant from what I have described?
