How long will menstruation delay after taking emergency contraception?

Emergency contraception may delay menstruation for 7 days to 1 month, but the specific time varies from person to person.

Emergency contraception contains high doses of progesterone, which can interfere with a woman's endocrine system, thus affecting the menstrual cycle. Different women respond differently to emergency contraception. Some women may only be slightly affected, delaying menstruation for a short time; for other women, there may be more obvious menstrual disorders, delaying time may take about 1 month.

If menstruation is delayed for too long, or accompanied by other abnormal symptoms, such as abdominal pain, abnormal vaginal bleeding, etc., you should seek medical advice, conduct relevant tests, such as ultrasound, sex hormone testing, etc., to rule out the possibility of other diseases, and under the guidance of a doctor for appropriate treatment and treatment.
