"Different menstrual colors represent different diseases" on the Internet
The saying has been circulating for a long time.
Many women can't help but sit in the seats.
The state of the body is judged by the color of menstrual blood.

What most people don't expect is that during menstrual bleeding, there is more than just "blood" that is excreted from the body. What you think is "abnormal color" is probably just letting menstrual blood carry the blame.
The composition of "menstrual blood" is not simple.
Menstruation is the result of periodic thickening and shedding of the lining of the uterus.
A woman's endometrium is divided into two layers: the basal layer and the functional layer.
The basal layer prevents intrauterine adhesions and is fixed. Ovarian hormones are affected by the functional layers of the endometrium.
During ovulation, the ovaries continue to secrete estrogen and progesterone, allowing the functional layers in the endometrium to be nourished.
After ovulation, the follicle will form the corpus luteum, the corpus luteum is the main progesterone, if the egg is not combined with the sperm, the corpus luteum slowly atrophies, the progesterone declines, and the endometrium loses progesterone support, and the functional layer of the endometrium will shrink and fall off, and bleeding will form menstruation.
Menstrual blood consists of three-quarters arterial blood, one-quarter venous blood, and some small, fleshy tissue in the functional layer of the intima. But what women observe on sanitary napkins is more than menstrual blood.
The shedding endometrial functional layer will be discharged from the uterus through the cervix from **, and along the way, it will also carry some other substances, such as a kind of adhesive secreted by the cervix and ** mixed secretion in order to protect ** and prevent dirt from entering-leucorrhoea.
So, every time you think the color of your menstrual blood changes, it may actually be affected by a mixture of vaginal discharge.
There is more than one color of menstruation.
Pink. In fact, the endometrium falls off every day during bleeding, and it doesn't fall off all at once.
Normally, when menstruation first comes, it is also when the functional layer of the endometrium has just fallen off, and the amount of menstrual blood is relatively small.
Bright red. Bright red color means that the menstrual period has entered its peak, the shedding of the endometrium increases, and the uterus will continue to contract at this time, and the amount of menstrual blood discharged will also increase.
At this time, menstrual blood accounts for the main proportion of the substances adsorbed by sanitary napkins, so what you observe will be the most common color, that is, the color of blood.
Dark red. Menstrual blood is excreted from the uterus through the cervix, but it is not always excreted in time.
If the menstrual flow is relatively small and does not flow out actively, it will gather in the uterine cavity or ** due to the slow flow rate. When the iron ions in the blood are oxidized, the blood turns dark red.
Brownish-red. If menstrual blood is expelled over a long period of time, it is deeply oxidized and will take on this color.
Towards the end of menstruation, dark blood mixes with secretions. Think about the color palette you played with when you were a child, black and red and white and yellow are added together, and brown will naturally appear.
What color of menstrual blood is worth being wary of?
Orange. Orange menstrual blood may be the result of an infection.
If you are infected with bacterial inflammation or a sexually transmitted infection caused by parasites, the vaginal discharge may appear yellowish-gray or yellowish-green, which changes the color of menstruation.
Gray Green.
Both bacillary and gonococcal inflammation can change the color of vaginal discharge, and when it mixes with menstruation, it can make menstrual blood look weird.
