First, dark red menstrual blood:

Although menstrual blood is bright red, the oxygen content of hemoglobin will gradually decrease after being "stored" on sanitary napkins for a period of time; In addition, in the acidic environment of vagina, iron in blood is easily oxidized, which darkens the color of blood. So what we usually see on sanitary napkins is "dark red" menstrual blood.

Second, bright red menstrual blood:

If the amount of menstruation is particularly large, the color on the menstruation towel will be "bright red". When the menstrual flow is large, it takes a short time for menstrual blood to flow out of the body. Before the blood is oxidized, another wave of menstrual blood will come out, and the menstruation towel will appear "bright red".

Third, light red:

Anemia, the content of hemoglobin is low, the color of blood will become lighter, and it will basically show a light red. At this time, it is necessary to go to the hospital to ask the doctor to help diagnose and recuperate.

Fourth, brown, black:

When the amount of menstruation is small, menstrual blood can't flow freely, but will stay in the vagina for a long time. Blood is easily oxidized, turning brown or even black. 　　

Menstruation is brown in color.

Menstruation is a normal physical and physiological phenomenon that every woman needs to experience. Generally, during menstruation, symptoms such as breast swelling and abdominal pain will easily occur, while normal menstruation will last for about 4-7 days, and the color of menstruation will be red. If menstruation appears dark brown, it proves that the body is in poor health, and there is qi deficiency or wet cold in the body, which can be recuperated by traditional Chinese medicine therapy.

Some women will only discharge a small amount of brown secretion, which usually lasts for 2~3 days, not more than a week at most, and may be accompanied by mild ovulation pain and low back pain. Under normal circumstances, the amount of bleeding during ovulation is relatively small, which has no effect on personal life, so there is no need for treatment; However, if the amount of bleeding is large, affecting daily life, and women aged between 20 and 40, a small amount of estrogen can be supplemented appropriately under the guidance of a doctor, which can alleviate this symptom.

Generally speaking, it is characterized by irregular menstrual cycle, more menstrual blood, prolonged menstrual period or irregular bleeding. The principle of treatment is to stop bleeding quickly, and adjust and establish a normal menstrual cycle after stopping bleeding to prevent recurrence. Some women may be accompanied by different degrees of anemia due to long-term functional uterine bleeding, so anemia should also be corrected.

This situation can be called "contact bleeding", which is mostly related to gynecological diseases such as vaginitis, cervical erosion, cervical polyp, early cervical cancer and submucosal myoma. It is recommended to go to gynecology as soon as possible.

The secretion is brown, which may be blood stasis in the uterus. There is also irregular menstruation due to qi deficiency and blood stasis. If you have dysmenorrhea, it can better explain that it is blood stasis left in the last menstrual period. Although the endometrium does not flow clean during menstruation, the remaining endometrial blood will be absorbed by the uterus again. But these dirty blood will stay in the uterus until the next menstrual period. For a long time, it is easy to cause blood stasis and menstrual pain, and it is also easy to cause uterine fibroids.
