Why does the day 'red light' last longer than usual?

Birth control pills, pre-menopausal, sexually transmitted diseases . can cause menstrual periods to prolong and lose a lot of blood.

According to Prevention, not all menstrual cycles are the same, so there's no need to worry."Women are definitely aware of what is normal for them," said Dr. Jennifer Ashton. If abnormal happens in 3 consecutive months, see a doctor.

Here are 7 reasons your red light days are heavy, bleeding more than usual.

1. Birth control pills

Hormonal contraceptives often regulate and reduce menstruation time, reducing blood loss. People who lose a lot of menstrual blood may be advised by their doctors to use birth control pills for abstinence. If you stop taking birth control pills or switch to medications that do not contain hormones, menstruation will become more severe. Although this is normal, see a doctor if the bleeding is more than 3 months long.

2. Pre-menopause

Menstruation often has many changes before menopause. You cannot predict the exact time of menopause but if your period is changing a lot, it could be a sign.

3. Anticoagulants

Using anticoagulants such as aspirin makes blood flow through the body easier but also makes the menstrual period more. The doctor will consider the type of medication that helps prevent this.

4. Coagulation disorder

Unusual heavy red lights can also be a sign of coagulopathy. There are many different types of blood diseases. About 2-4 million Americans suffer from Von Willebrand disease, due to a deficiency or decrease in the activity of a hemostatic protein.

5. Uterine fibroids

Uterine fibroids are small tumors, not cancer inside the uterus. This situation is more common than you think. Research from Birmingham Women's Hospital in the UK shows that 70% of women experience this condition at age 50 and older. One of the main symptoms of uterine fibroids is severe bleeding, sometimes with blood clots or vaginal bleeding between cycles.

6. Polycystic ovary syndrome

This syndrome occurs in 10% of women and most women do not recognize it. The menstrual cycles of these people are often disordered, bleeding or prolonged.

7. Sexually transmitted disease

Sexually transmitted diseases such as gonorrhea, chlamydia or any infection on the lining of the uterus can cause severe bleeding. If you have had unprotected sex and noticed abnormal periods, you should see your doctor early.
