How long does it take for menstruation to come after withdrawal bleeding from taking birth control pills

Emergency contraception is an important way for women to avoid unwanted pregnancy at this stage. Some women also take emergency contraception to help us delay the onset of menstruation. However, long-term use of emergency contraception is harmful to our body. Emergency contraception will first cause irregular menstruation. Next, let's see how long it will take for menstruation to come after withdrawal bleeding from taking birth control pills?

How long does it take for your period to come after taking birth control pills and withdrawal bleeding?

Many female friends are concerned about whether taking birth control pills will affect their menstrual periods. Generally speaking, emergency contraception will not have a significant impact on menstruation, but if it is taken for a long time or in large quantities, it may cause irregular menstrual cycles, even amenorrhea or infertility. If you are taking birth control pills, you will still have a small amount of vaginal bleeding and your menstrual cycle will also change.

The delay or early menstruation caused by emergency contraception is mainly because women do not take it according to the instructions. If emergency contraception is used strictly according to the instructions, it will generally not cause changes in the menstrual cycle. In addition, a small number of women are more sensitive to drugs and may experience vaginal bleeding after taking birth control pills, but it will not happen every time, so there is no need to worry too much. This is mid-menstrual bleeding caused by the effect of the drug and is a normal phenomenon. Taking birth control pills can affect your menstrual period. At present, the safest and most effective way to delay menstruation is to continuously take small doses of short-acting contraceptives, such as Usina and Marvelon, and it is best to take the medicine one month in advance, otherwise it will be difficult to ensure the "delay" effect.

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.

Will taking birth control pills bring your period forward?

Menstruation is generally delayed after taking birth control pills, but there are some cases where menstruation comes early. Taking birth control pills ahead of schedule usually causes similar early pregnancy reactions, such as drowsiness, nausea, and vomiting. Some people who are sensitive to drugs have more obvious reactions.

If pregnant women take emergency contraception at different times of their menstrual cycle, the effects on their menstrual period will also be different. If taken within the first half of the menstrual cycle, it may have a great impact on women's menstrual period and vaginal bleeding may occur; if taken within the first half of the menstrual cycle, it will have less impact on women's menstrual period. Because of individual differences, patients' responses to special contraceptive pills vary. A very small number of women will experience vaginal bleeding within a short period of time after taking the medicine. If the bleeding is similar to normal menstrual flow, it can be regarded as a menstrual period, and basic contraceptive measures should be taken immediately after the bleeding stops. If the bleeding is very little, you don't need to do anything, but you still need to pay attention to contraceptive measures until the next menarche.
