Bleeding a week before your period

Menstruation is the monthly menstrual period for women. Basically, women’s menstruation will be more regular after adulthood. As long as they have good living habits and regular work and rest schedules, there will be no problem with menstruation. However, it cannot be ruled out that other factors may interfere and cause problems. When problems with menstruation occur, female friends should find out the cause and receive targeted treatment, because menstruation affects future fertility. A detailed introduction to what causes bleeding one week before menstruation.

1. Starting, stopping or changing birth control pills: Premenstrual bleeding may be caused by women just starting to take birth control pills or using different birth control pills. Birth control pills reduce the production of estrogen in the reproductive organs. Estrogen and endometrial shedding are closely related. Birth control pills can cause your body's estrogen levels to become unstable, so when you start, change, or stop using birth control pills, you may experience premenstrual bleeding. But in general, when you use your birth control pills correctly, or stop using them, the symptoms of premenstrual bleeding will gradually return.

2. Menstrual disorders: Many people have experienced menstrual disorders. For most people, when we first start menstruating, the cycle is very irregular, especially the first time. Some people's menstrual periods may gradually become normal and regular, but some people's menstruation becomes more and more irregular, and sometimes they bleed before their period. The main reason is estrogen disorder in our reproductive system, which can also be said to be menstrual disorder, causing the endometrium to shed slightly during the non-menstrual period.

3. Thyroid disease: Studies have shown that thyroid disease is also an important cause of premenstrual bleeding. If you experience bleeding before your period, you may have thyroid problems. Think about whether you feel more tired and colder than usual, gain weight for no apparent reason, lose your hair, or notice tenderness in your neck. Thyroid disease is not a terrible disease. In fact, it is a very common disease that can be treated with medication, which can also improve the symptoms of premenstrual bleeding.
