How long does it take to correct menstrual irregularities after taking birth control pills?

Generally speaking, taking birth control pills will cause menstruation to be delayed by within a week. Emergency contraception is a hormone that is mainly composed of estrogen and estrogens, and its side effects are affected by the health status of the person taking the medicine. Most women will still have regular menstruation after taking emergency contraception. A small number of women will experience delayed or early menstrual cycles due to the effects of estrogen and estrogens on the body's endocrine system, but the delay will not last long. Generally within a week, if the menstruation is delayed for more than a week, a urine HCG test should be performed to check whether you are accidentally pregnant. If the menstruation is delayed for more than 20 days and pregnancy is not confirmed, it is necessary to go to the hospital for treatment.

After taking emergency contraception, delayed menstruation generally affects the next menstrual cycle. In other words, the menstrual cycle can be restored after one month. Taking emergency contraceptives can cause delayed menstruation, most of which are caused by taking birth control pills, which can cause a temporary increase in female hormones in the blood, inhibit ovulation and the function of the uterine wall, and have a certain impact on the next menstrual period. However, as the level of estrogen decreases, the body will gradually return to normal estrogen levels, and the menstrual period will naturally resume. After taking it for one month, menstruation will basically return to normal.

Emergency contraception will affect the menstrual cycle. Contraceptive pills contain low doses of growth hormone. Some women will experience menstrual cycle disruptions, changes in menstrual periods or changes in menstrual volume after taking the pills. Ovulation will also be affected by changes in menstrual periods, and the longest delay is generally 7-10 days. If it hasn't come for more than 10 days, it is recommended to go to the hospital for a physical examination to prevent delaying the condition and causing harm to the body. According to calculations, assuming that the period comes on June 15, the normal menstrual cycle is 28 days. To delay menstruation, you can start taking small doses of short-acting contraceptives on May 15 (the first day of menarche in the previous month), 1 tablet a day, and continue taking the medicine until after June 15. Withdrawal bleeding can occur 2-3 days after stopping the medicine. In this way, menstruation can be successfully delayed. Women with irregular menstruation can also start taking the medicine on the first day of menstruation in the previous month.

Taking birth control pills can maintain and increase the metabolism of the uterine wall and prevent it from exfoliating, thus achieving the purpose of delaying menstruation. If you are troubled by your menstrual cycle during important occasions such as honeymoons, beach vacations, exercise or competitions, you can try this method. When taking various emergency contraceptives, you must develop a good habit of taking them accurately, on time, and in the prescribed dosage. You cannot change or increase the time of taking the medicine at will. Do not miss or take the dose late. If you miss a dose, take it the next day. Otherwise, it may cause non-menstrual bleeding or accidental pregnancy. For long-term contraception, it should be taken under the guidance of a physician. The recommended duration of medication is generally 6-7 years for short-acting drugs and 3-4 years for high-efficiency drugs.
