What is the reason for the grayish black color on the last day of the menstrual period?

It is normal for the blood to be black on the last day of menstruation. Vaginal bleeding may be black at the beginning and end of menstruation when a woman has her first menstruation. At the beginning and end of the menstrual period, the woman's uterine wall will peel off very little, the wound will be small, and the amount of vaginal bleeding will be very little. A small amount of uterine wall and blood have a weak stimulating effect on the uterine muscle layer. The contraction ability of the female uterine muscle layer is weak and the pressure is relatively small. It will take a long time for the blood and exfoliated uterine wall to be discharged from the body. The retained blood will gradually be oxidized and coagulated and easily turn into gray-black. Most patients do not have clinical discomfort such as abdominal pain. On the 2nd or 3rd day of your period, vaginal bleeding will increase as the amount of uterine wall shedding increases, and the color of the bleeding will be red.

What are the normal colors of menstrual blood?

Strictly speaking, the color of normal menstrual blood is not one color at all, but there are multiple colors, and the colors are definitely different under different circumstances. The most direct influencing factor is the proportion of venous blood and arterial blood in menstrual blood... dark red, white, dark brown, gray and black... these colors may all be normal. The less blood there is in the menstrual blood, the darker the color. The longer the menstrual blood flows, the darker the color and the stronger the properties. If the menstrual blood discharge channel is not smooth, blood clots will form and even cause menstrual pain.
