The female menstrual cycle in women with regular periods begins on the first day of the period and usually lasts 28 days, although some women have cycles of 21 and 35 days. When vaginal bleeding occurs between periods, bleeding is not associated with menstruation. It is an abnormal fact related to many factors and conditions. It is essential to know its cause to prevent complications throughout the device female reproductive.

These bleeds between periods are more common in women with irregular periods. In most cases is caused by some factor or pathology that triggers a hormonal disorder that alters the functioning of the uterus and causes breakthrough bleeding. Most women are alarmed by this symptom. However, it is one of the most common reasons for visiting a gynecologist, and it is not always associated with the existence of a dangerous disease. Examining the uterus, ovaries, performing hormonal tests, and a Pap smear (cytology of the cervix) is necessary to determine the causes of vaginal bleeding between periods. We invite you to continue reading this FastlyHealarticle, where we report why bleeding occurs between rules.

Contraceptives

The consumption of contraceptive pills generates a reaction of chemical origin in the organism that, in many cases, alters hormonal production. For this reason, when a woman begins to consume oral contraceptives or has just changed pills, bleeding between periods is likely to occur as a consequence of the new hormone that is being supplied to the body or as a sign that this contraceptive is not the one that suits that woman the best. This condition is known as pill spotting between periods and can also be caused by the intake of hormonal medications. Changing the pill or increasing the hormonal dose usually resolves the symptom.

Other contraceptives that usually cause vaginal bleeding are intrauterine devices (IUD). Since being placed directly in the uterus, abuse during insertion will likely cause minor bleeding. In addition, the woman’s body, especially if it is the first time that she uses this type of contraceptive method, usually gets used to the IUD during the first three months, a period in which the uterus can fight through contractions to expel the foreign organism, which can cause bleeding or light breakthrough bleeding. Among the side effects of these contraceptive methods, vaginal bleeding can last between 3 months and up to a year.

Hormonal problems

Among the causes of vaginal bleeding between periods, the most common is some hormonal disorder in the body that alters the menstrual cycle or can even cause a woman with regular periods to have irregular periods or a total absence of the rule. When hormones are responsible for this disorder, gynecologists call it dysfunctional uterine bleeding, more common in newly developed adolescent women and very adult women nearing menopause.

Changes in birth control pills or oral hormone therapy can also trigger breakthrough bleeding. Likewise, stress is one of the factors that can most unbalance hormonal production. For this reason, emotions such as sadness, fears, anxiety, anguish, and depression can alter menstrual cycles at a certain point in life and cause bleeding between rules. Women who have problems with the thyroid gland, either from hypothyroidism or hyperthyroidism, also often have abnormal vaginal bleeding due to gland malfunction.

Pregnancy-related conditions

Ectopic pregnancy

In pregnancy, when the egg is fertilized, it travels through the fallopian tubes to the uterus. If it encounters an obstacle during the transit of the ovum, an ectopic pregnancy occurs. That is, it develops outside the womb. This scenario is dangerous for the mother, and the main symptom is abnormal vaginal bleeding.

Spontaneous abortion

Any bleeding during pregnancy should be a red flag. Miscarriage occurs before the 20th week of pregnancy and, in most cases, occurs when the woman still does not know she is pregnant. Problems with the uterus or cervix are usually one of the leading causes of miscarriage, with abnormal vaginal bleeding as its main symptom.

Conditions of the female reproductive system

Pelvic inflammatory disease

PID consists of infection and inflammation of the uterus, ovaries, and other parts of the female reproductive system that cause scars, one of the leading causes of infertility. Extreme pelvic, abdominal pain, and bleeding between periods are symptoms of this condition.

Uterine fibroids

They are the most common non-cancerous tumors that appear in the uterus of women of childbearing age and are made up of muscle cells and other tissues found in the uterine wall. Although many women with uterine fibroids have no symptoms, this condition often causes heavy and painful periods, breakthrough bleeding, lower back pain, and fertility problems.

Cervicitis

It is the inflammation of the cervix produced in most cases by a sexually transmitted infection such as chlamydia, gonorrhea, genital herpes, trichomoniasis, or human papillomavirus. Devices like the hood and IUDs can also cause this tissue to swell. Abnormal vaginal bleeding is the main symptom of this condition and can occur between periods or after sexual intercourse. When an STD causes cervicitis, it is usually accompanied by white, yellow, or gray discharge.

Hiperplasia endometrial

It occurs when the tissue of the uterus, better known as the endometrium, becomes too thick, usually due to an excess of estrogen and a lack of progesterone. This condition usually occurs after menopause and needs to be treated early to prevent it from triggering uterine cancer.

Polycystic ovary syndrome

When the ovaries or adrenal glands produce more male hormones than average, cysts form on the ovaries, which is more common in women with overpressure or insulin resistance. The main symptoms are pelvic pain, irregular periods, bleeding between periods, acne, and brown patches on the skin. This condition is often resolved with the use of birth control pills.
