A member asked:

If i didnt ejaculate in my partner and still gave her plan b, why hasnt she received her period yet? its almost the end of the month

A doctor has provided 1 answer

Hard to say: Any erect penis is transferring sperm continuously during sex. It only takes one to get pregnant. Plan b is usually effective if given within 72 hrs. It can fail. She could also just be late which some women do occasionally.
