Patient's question:
I passed a sexual life yesterday and don't know how long the effect of emergency contraception will last. How long does the effect of emergency contraception last?Doctor's answer:
The hormone content of emergency contraception pills is very similar to that of 8 days of regular contraceptive pills. After taking them, menstruation may be advanced or delayed by one week, still within the normal range. Emergency contraception pills are not 100% effective. There is about a 2% failure rate with breastfeeding. If menstruation is delayed by less than 10 days, it is necessary to consider the possibility of an unexpected pregnancy and seek medical examination. If your menstruation is currently delayed but not by less than 10 days, do not be overly anxious and focus on careful observation. Excessive worry and anxiety can suppress the function of the hypothalamus, leading to delayed menstruation.
