long period

The length of the menstrual period can vary significantly between different women, but in general, gynecological experts have established that a normal duration ranges between 3 and 7 days.

When the duration of menstruation is below or above this recommended range, it is advisable to seek guidance from a gynecologist to identify the possible causes behind a period that is too short or, on the contrary, excessively long.

Why does my period last so long?

There are several reasons why your period can last so long and here we address different causes:

Hormonal imbalance

During the menstrual cycle, levels of hormones such as estrogen and progesterone fluctuate to prepare the body for a possible pregnancy. If these levels are unbalanced, they can affect the length and intensity of the menstrual period.

Absence of Ovulation

When the ovulation process does not occur during the menstrual cycle, the bleeding that is subsequently eliminated during the days of menstruation can extend and become more abundant.

Polyps in the inner lining of the uterus

Uterine polyps are non-cancerous developments in the inner lining of the uterus, which when they increase in size can cause symptoms such as abnormal vaginal bleeding, heavy and prolonged menstruation, anemia, discomfort and complications in conception.

Faced with these signs, it is essential to go to the gynecologist to evaluate whether a hysteroscopy is required, a surgical intervention used to eliminate this type of growth.

Presence of uterine fibroids

Another common cause of long periods is the presence of uterine fibroids. Fibroids are benign tumors that grow in the wall of the uterus.

Although they are not cancerous, they can cause a series of symptoms, such as your period being prolonged and heavy. This is usually accompanied by pelvic pain and abdominal pressure.

Use of the Intrauterine Device (IUD)

Under certain circumstances, the use of an intrauterine device (IUD) as a contraceptive method can cause side effects, and one of these possible effects could be menorrhagia. If you experience this situation, it is advisable to seek specialized medical advice, as it may be necessary to consider removing the device and evaluating alternatives regarding contraceptive methods.


Endometriosis may also be an explanation for why your period lasts so long. This condition occurs when tissue that normally grows inside the uterus begins to grow outside of it and does so in other pelvic organs.

This condition can cause painful and prolonged periods, as well as other symptoms such as pain during sexual intercourse and chronic pelvic pain.

Sexually Transmitted Diseases (STDs)

Sexually transmitted diseases can also affect the length of the menstrual period. Chlamydia and gonorrhea, for example, can cause inflammation in the cervix, which can lead to longer, more painful periods.

certain medications
