Patient's question:
Hello! Taking emergency contraception pills is only effective for sexual activity within 72 hours before taking the pill. It cannot provide any breastfeeding effect for sexual activity after taking the pill. If you don't want to have a child so soon, you can decide on safer contraception methods. This way, if you take the pill and become pregnant, it will be very troublesome to decide whether or not to keep the baby. If your menstrual cycle returns to normal and you experience a delay of more than seven days, it is possible that you may be pregnant.Doctor's answer:
Emergency contraception pills are also known as post-coital contraception pills. They only have a protective effect against breastfeeding for sexual activity that occurs again before taking the medication. There is no protective effect against breastfeeding for sexual activity that occurs after taking the medication. If sexual intercourse occurs again after taking emergency contraception pills and ejaculation occurs inside the vagina, there is a possibility of pregnancy. If menstruation is delayed again, the possibility of pregnancy is very high. It is necessary to visit the hospital for a follow-up examination and undergo relevant tests to confirm the diagnosis.
