If you are curious and want to know more about the causes and risks behind black menstrual blood, don't miss the complete explanation below!
Is Black Menstrual Blood Normal?

To answer whether dark black menstrual blood is normal or not, you first need to know the menstrual process.
In the early phase of menstruation (follicular phase), estrogen and progesterone hormones thicken the endometrial lining of the uterus. This thickened lining is ready to become a vessel for fertilized eggs to attach and develop into a baby.
However, if no egg attaches after some time, this tissue will begin to break down and shed. This damaged and shed tissue will then come out together with blood through the vagina, resulting in menstruation.
When the shedding process occurs, the blood still in the uterus will undergo oxidation, causing its color to become darker over time. This is the reason why menstrual blood can appear black.
There are two possibilities that can explain this. First, black menstrual blood on the first day is leftover blood from the previous period that was trapped and finally came out when the new period started. While black blood at the end is the last blood from the cycle that has been oxidized while inside the body
If this is the scenario you are experiencing, then black menstrual blood is normal.[1] Even so, there are several other causes to be aware of, as they can be related to more serious health problems.
Causes of Black Menstrual Blood
What does black menstrual blood indicate? Besides the beginning or end of the menstrual period, there are several other causes that can make menstrual blood black, including:
1. Vaginal Infection Due to Foreign Objects

Foreign objects such as tampons or contraceptive devices in the vagina can injure the vagina and cause black blood to come out. This condition is generally also accompanied by fever, a foul-smelling and itchy private area, and discomfort when urinating.
2. Sexually Transmitted Diseases

Unsafe and unprotected sexual activity can open the door to the transmission of sexually transmitted diseases.
Among the infections that occur frequently, chlamydia and gonorrhea are two types of diseases that can irritate and damage the genital organs. This condition not only causes discomfort but can also trigger wounds in the sensitive area.
3. Implantation Bleeding

Black and clotted menstrual blood can also be triggered by egg fertilization. When the egg is finally fertilized and attaches to the uterine wall, this activity can cause slight bleeding that lasts up to two days.
When the blood from this bleeding is trapped and oxidized, the blood will come out black later. Given that this condition occurs in the early phase of pregnancy, which you may not yet realize, you may consider it a normal period.
4. Cervical Cancer

Unusual changes in menstrual blood color can be one of the signs of cervical cancer. This disease often appears with several other symptoms, including hip pain, longer and heavier periods, and sharp pain in the lower abdomen.
5. Hematocolpos

Black and foul-smelling menstrual blood can also occur due to the accumulation of blood in the vaginal canal that cannot flow out properly and smoothly.
When the blood is trapped for too long, the oxidation process will cause the blood color to become darker. This is a natural reaction when blood is exposed to oxygen for a certain period of time.
This accumulation of blood can cause discomfort, and it often smells unpleasant because the blood is trapped longer than usual.
