Usually, red-coloured discharge is seen during periods. The colour of the discharge may turn black sometimes though, which makes most women a bit nervous. However, the presence of black-coloured blood during periods is not a matter of concern. Most of the time, this happens when the blood is not able to come out of the uterus at the right time, as the blood gets oxidized and the red-coloured discharge turns dark, brown or black in colour.

Note that there can also be some serious reasons for the presence of black-coloured blood during periods, so women should contact the doctor with their concerns before dismissing them. In this article, we will share some reasons behind black blood discharge during menstruation.

Causes of black blood in periods

Early pregnancy

Some women experience dark-coloured blood discharge at the beginning of pregnancy. This happens because the embryo attaches itself to the wall of the uterus. However, during pregnancy, if women also experience symptoms like dizziness, fatigue, shoulder pain, etc, then it can be a sign of miscarriage. In this case, a doctor should be contacted immediately.

Hormonal changes

It’s common for women to go through many hormonal changes in their life. When women face problems of the thyroid or menopause, instead of red-coloured blood, black-coloured blood may be noticed during periods. However, the amount of such blood is very small. (Read more: Hormonal imbalance)

Emotional changes

It is natural for women to experience emotional changes. When women suffer from emotional and mental health conditions such as stress or depression, the thickness of the lining of the uterine walls can decrease and the structure of the uterus can be affected. Due to this, the cells start their work late and there may be black-coloured blood during periods.

Endometriosis

Endometriosis is a disease related to the uterus, in which the endometrial tissue grows abnormally and spreads outside the uterus. If it occurs, you may experience symptoms like pain in the pelvic area, fever etc. During this period, black blood may be seen during menstruation. This can last for 6 to 7 days and in such cases, it is necessary to contact the doctor. They treat this problem either with antibiotics or through surgery. (Read more: Period pain)

Sexually transmitted diseases

Gonorrhea and chlamydia are diseases that are caused by bacteria and fall under the category of sexually transmitted diseases (STDs). This disease can darken the blood discharged during periods. Along with this, women can also experience problems like fever, pelvic pain or foul smell.

Cervical cancer

While it is very rare for black bleeding to be a sign of cervical cancer, for many women, irregular bleeding during periods or after sex is the most common sign of cancer, while others include dark blood discharge, weight loss, fatigue, pelvic pain, swelling in the legs, trouble urinating or defecating, etc. (Read more: Vaginal cancer)

Takeaway

You should not panic if you notice black-coloured blood during your period, but it’s important to keep an eye on any other symptoms that show up along with it and contact your doctor without delay.
