Okay so I've had to take plan B three times now in my life (last night being the third). He came inside me and I felt a really warm sensation when he did (it was an accident , he came while pulling out) and I took plan B two hours after. I've read that the more times you take plan B , the less effective it becomes to your body so that's why I'm worried since it was the third time taking it. Do you think I'll be okay or should I worry?
