What causes bleeding a week before period?

For women, the monthly visit of menstruation is really annoying, because during this period not only the physical strength is relatively poor, but also abdominal pain is prone to occur. In addition, there are many taboos during menstruation, such as not eating raw or cold food and not wearing too little, etc. So the question is, some women find themselves bleeding a week before their period, what's going on?

Bleeding one week before period

Premenstrual bleeding is a type of premenstrual syndrome. When you think your period has not arrived yet, or it is still a few days away, you think you can swim and exercise safely, but after going to the bathroom, you unexpectedly find that you have already bled a small amount before the next period starts. So, this premenstrual bleeding can seriously disrupt our plans and mood, and our white pants may also be stained. So what causes premenstrual bleeding?

Causes of premenstrual bleeding

1. Start, stop or change the use of birth control pills

Premenstrual bleeding may be caused by a woman just starting to take birth control pills or using a different birth control pill. 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. Sickness

You shouldn't take bleeding before your period as a sign of something serious, but in some cases it can be a sign of a health problem - including pelvic inflammatory disease, miscarriage or cervical cancer. If your symptoms can be adjusted through diet and lifestyle changes, there is no need to spend time worrying about these things, but you need to judge based on your overall health during this period of premenstrual bleeding. If you are really worried, go to the hospital for a check-up!

4. Thyroid disease

Studies have shown that the thyroid gland 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.
