Sir, I had sex with my fiance (tearing of condom occurred) a day before her normal period date (She generally has 30 days cycle. I gave her an Unwanted 72 tablet within 10 hours just to be on the safe side. And now she didn't get her period yet. And its almost 4 days late to her proper date. Why is it late? And how late it can be? P.S. - It was just a day or two before her period date. So I don't think there were much chances of her getting pregnant.
