Question

Quizplus · Accepted Answer

Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, but can be taken up to 120 hours (5 days) later. Option B is incorrect because emergency contraception works by preventing ovulation or fertilization, so it is most effective before ovulation occurs. Option C is incorrect because the effectiveness rate of emergency contraception is actually much higher, closer to 75-89%. Option D is incorrect because while some women may experience changes in their menstrual cycle after taking emergency contraception, menorrhagia (excessive menstrual bleeding) is not a common side effect.
