I take the pill every day at the exact same time. Last Saturday night, long story short, my boyfriend and I were fooling around in the shower, and he started rubbing his shaft against me (not his tip). When he came away he had dripped some pre-ejaculate on my pubic mound, so when I stood up I tried to angle my body in a way that the shower water wouldn't rinse the liquid down into me. Ever since then, I've been so stressed and sick because I was cramping the next morning, and Monday afternoon I even took a plan B pill because I'm so scared. What are the odds that my birth control failed even though I take it literally the same time every day, that there were sperm in his pre-ejaculate, that they could have gotten into me, and the plan B failed? What are the odds I could be pregnant? Please help! Also, will I even have a period because of the plan B? I really hope I'm just being paranoid...
