Emergency contraceptive pills and menstruation?
Doctor, if a woman has her period before taking the "emergency contraceptive pill" within 72 hours after sexual intercourse, does she still need to take the "emergency contraceptive pill"? Thank you.

More Info
If your period has started after unprotected intercourse, you generally do not need to take emergency contraception (EC). Emergency contraception is designed to prevent pregnancy after unprotected sex or contraceptive failure, such as a broken condom, and is most effective when taken as soon as possible after the incident, ideally within 72 hours. However, if your menstrual period has begun, it indicates that your body is going through its normal cycle, and pregnancy is unlikely.
To elaborate, the menstrual cycle typically involves the shedding of the uterine lining when pregnancy does not occur. If you have started your period, it means that the hormonal changes in your body have triggered this process, and it is a sign that you are not pregnant. The onset of menstruation is a strong indicator that the egg released during ovulation was not fertilized, and therefore, there is no need for emergency contraception.
It's important to note that the timing of your menstrual cycle plays a crucial role in understanding your risk of pregnancy. If you had unprotected sex during your fertile window (which is usually around ovulation), there is a higher risk of pregnancy. However, if your period has started, it suggests that ovulation has already occurred and that the egg was not fertilized.
In addition, if you are experiencing any unusual symptoms or changes in your menstrual cycle, it may be worth consulting with a healthcare provider. They can provide guidance on what to expect during your cycle and address any concerns you may have regarding your reproductive health.
In summary, if your period has started after unprotected intercourse, there is no need to take emergency contraception. However, if you have any doubts or if your menstrual cycle is significantly irregular, it is advisable to seek medical advice for further evaluation and peace of mind. Always remember that regular use of contraception is the best way to prevent unintended pregnancies and to maintain reproductive health.
