I don't think I got semen on my vulva as there was no penetration but could be accidental touch there with the penis, so to be sure I took unwanted-72 tablet after 25 hours, (my periods ended 1 day before I had sex), and I got bleeding just like my normal periods after 5 days of taking the tablet which lasted 4 days.(right around 13-15 days into my cycle), but now it's 11 days after my normal period date, is it normal for this much delay? Because I got bleeding just like normal periods after 5 days of taking the pill.
