When will my period come after taking emergency contraceptive pills?

When adult men and women are together, it is inevitable that there will be moments of passion. If contraceptive measures are not taken during the passionate moment, it may lead to pregnancy. Therefore, people who do not want to get pregnant will often take emergency contraceptive pills to prevent pregnancy after the passion. However, some people experience irregular menstruation after taking emergency contraceptive pills, and some people do not have menstruation for a long time. Is this normal? When will menstruation come after taking emergency contraceptive pills?

Contraceptive pills can cause menstrual irregularities in women. If taken in the first half of the menstrual cycle, the side effects of emergency contraceptive pills may interfere with women's menstruation and cause vaginal bleeding. If taken in the second half of the menstrual cycle, the interference with women's menstruation will be smaller.

If the amount of bleeding is similar to normal menstrual flow, it can be regarded as a menstrual period. Conventional contraceptive methods should be adopted immediately after the bleeding stops. If the amount of bleeding is small, no treatment is needed, but you still need to pay attention to contraception until the next menstruation.

Experts say that contraceptives contain very high levels of estrogen. Taking too large a dose can lead to menstrual cycle disorders, ovarian suppression and other phenomena, disrupting normal menstruation and causing endocrine disorders. Contraceptive pills can cause endometrial hypoplasia and insufficient glandular secretion, so the endometrium cannot grow normally and becomes thinner, resulting in reduced menstrual volume. Some women experience amenorrhea due to excessive inhibitory effects of contraceptives, which results in no withdrawal bleeding after stopping the medication.

Generally speaking, menstruation will be delayed by about one week after taking birth control pills. The delay time will vary depending on individual physical conditions. If it is delayed for 20 days, it is recommended to see a doctor to determine whether emergency contraception has failed.

Taking emergency contraceptive pills may cause women's menstruation to become abnormal, usually delayed by one week. Of course, if you have sex again after taking birth control pills, it may also lead to contraceptive failure. Therefore, when menstruation is delayed, you need to check to see if your contraceptive has failed.
