Several changes may also happen against the normal menstrual cycles raising worries among women. Apart from pain and cramps, they may develop black period blood.

The black period blood is a common phenomenon among ladies and almost every one of them who experiences menstruation has observed that type of blood. The reason why the blood may develop that color as opposed to the known bright red color is because the blood from the period could have been withheld in the body hence oxidized.

Why is my period blood black?

 Here are some of the causes

Enlarged Uterus

Enlarged uterus occurs after pregnancy. It happens when the uterus fails to return to its normal size. The enlarged uterus allows the menstrual blood to accumulate before it is discharged out as a dark blood. Enlarged uterus may be as a result of cancer or fibroids. Enlarged uterus resulting from subsequent pregnancy is common.


Obstruction of menses

Obstruction of the blood flow may lead to the blood retention in vagina. Retention of blood in the vagina is as result of the hymen completely covering the vagina hence preventing blood flow. The flow happens after the contractions of the uterus forcing the blood to come out. For older women the narrow cervix could be the reason. Medication at the right moments may be required at both situations.


Vaginal infection

Black brown period may also result because of the vaginal infection. The vagina has several bacteria and any growth from them may lead to infection. Also sexually transmitted diseases may be the reason. When there is an infection there will be a bad odor during the discharge and pelvic pains may follow.

It is another possible cause of darkening of the blood. It happens when the tissues that forms the uterine walls develops outside the uterus. Almost similar condition known as adenomyosis may cause the condition. It happens when the tissues grows up in the muscles that forms the walls of uterus.



This could be another possible reason for the black blood.  For ladies who are expecting pregnancy and experience unusual periods, miscarriage could be the reason. Light discharge of blood is a common occurrence during the onset of the pregnancy. In some instances, abortion could be the reason.



Those women who are undergoing depression and stress may experience the black blood period. Depression and stress causes the interior walls of the uterus to be thin. When the walls of the uterus are thin, there is a likely hood of delayed shedding of the walls of uterus when the period begins.


Contraceptive pills

Those ladies who are under family planning and takes contraceptive pills have higher chances of experiencing the black period blood. This is always as a result of discoloration of the blood being expelled.


Delayed period

Delayed period is the major reason for the black period blood. Normally it is the remaining blood being expelled out and it is very normal.



Vaginal ultrasound may be ordered by the doctor to check for any disorders around the pelvis, uterus and ovaries. MRI also may be performed to check if there is presence of fibroids. In some cases biopsy test may be performed whereby a sample of uterine wall is extracted for further analysis.



Discharging of the black blood during period is a common occurrence. However, the cause of the black blood should be established to rule out any underlying problem. Experiencing severe pain and fouls smell while discharging the black blood could signify underlying problem. Seeking medical consultation from a gynecologist is advised.

More over women do experience heavy discharge of the thick and dark blood. Temporary heavy bleeding should not cause panic. However frequent heavy bleeding with presence of dark blood should be a reason to pay a visit at the hospital.
