The color of period blood is one of the important and significant signs in women's menstrual cycle, which provides valuable information about body health, hormonal status, and uterine function. Many women experience changes in the color of their blood during their periods. These changes may range from bright red to brown, black, pink, or even orange. In general, changes in the color of menstrual blood depend on various factors such as hormonal balance, infections, the use of certain drugs, and even lifestyle.

ToggleWhy does the color of period blood change?
Changing the color of period blood is a natural and expected process in the menstrual cycle of women, which mainly depends on the time the blood stays in the uterus and its contact with oxygen. When the blood comes out of the uterus quickly, it is usually bright red in color, but if this blood remains in the uterus or vagina for a longer time, the hemoglobin in it oxidizes and turns into darker colors such as dark red, brown, or even black. In simpler terms, the difference in the color of period blood is not the type of bleeding, but depends on the duration of the blood's presence in the body and its decomposition rate.

For example, the low level of estrogen may cause the blood to be diluted and its color pink, or the combination of blood with vaginal discharge can make its color orange. For this reason, changing the color of menstrual blood is not always alarming, but paying attention to recurring patterns or sudden changes can be a warning sign of the body's health condition that needs to be checked by a doctor.
The color of period blood is black
Sometimes women encounter black blood during their periods, which may cause concern. The cause of black blood in a girl's period is usually related to the accumulation of blood in the uterus and the delay in its exit. When the blood stays in the uterus for a long time, it receives more oxygen and as a result, its color becomes darker. This condition is more common in young women, especially girls who have just entered their period.
Blackening of menstrual blood can have various other reasons. The most important reasons for black blood during menstruation are endometriosis (growth of the inner tissue of the uterus outside it), pelvic or uterine infections, obstruction or stenosis of the cervix (this condition prevents the rapid outflow of blood), hormonal imbalance (decrease in estrogen or increase in progesterone) and early miscarriage. Remember that the presence of a blood clot during your period can be a sign of uterine fibroids or polyps.The cause of black period blood on the first day
The dark color of period blood on the first day is usually caused by the remaining menstrual blood from the previous cycle in the uterus, which is excreted at the beginning of the new period. This phenomenon is often normal, but if it repeats continuously every month and is accompanied by other symptoms such as severe pain or an abnormal smell, it should be checked by a doctor.

As we said, dark and black blood during periods is usually caused by menstrual blood staying in the uterus for a long time. When the blood stays in the uterus for a while without oxygen, a process called oxidation occurs and the color of the blood changes from red to dark brown or black. The cause of black blood in a girl's period also goes back to the same issue. However, if the dark blood is accompanied by unusual pain or large clots, be sure to see a doctor.
The color of period blood is brown
Brown blood is usually a sign of old blood that is excreted at the end of menstruation or sometimes at the beginning. Sometimes the brown color of blood during menstruation is also related to hormonal changes. If the brown color is accompanied by a bad smell or nausea during your period, you should seek help from a doctor as soon as possible for treatment.
Orange colored blood in period
Orange colored blood is less common than other colors during periods, so it is a little worrying for most women. This color usually appears when menstrual blood mixes with cervical or vaginal secretions, in such a situation, it takes on an orange color due to dilution or changes in its texture. If this color change is observed only in the first few hours of the period and is not accompanied by any other abnormal symptoms, there is usually nothing to worry about and it can be considered part of the body's natural changes.
If orange blood is accompanied by symptoms such as foul odor, itching, burning, or foamy and thick discharge, it may be a sign of a vaginal infection, such as bacterial vaginosis or sexually transmitted infections (such as trichomoniasis). In such a situation, it is very important to make a timely diagnosis and visit a gynecologist to perform the necessary tests. Paying attention to other period symptoms and checking recurring patterns in the monthly cycle can help to better diagnose the cause of this color change.

In some cycles, menstrual blood may be very light and pale red or pink. This condition is normal in many cases, but if it is repeated constantly, it may be related to a disturbance in the level of estrogen or a decrease in blood concentration. This issue is also seen in female athletes or people who have severe weight loss.
Reasons for changing the color of period blood
Changing the color of menstrual blood is normal, but if these changes are sudden, continuous or accompanied by unusual symptoms, it is necessary to be checked by a doctor. In the rest of this section, we mention some important reasons for the color change of period blood:
Permanence of blood in the uterus
The length of time blood stays in the uterus can directly affect the color of period blood. In many cases, period irregularity and inappropriate ovulation cause a delay in endometrial shedding and blood remains in the uterus. In this condition, the blood stays in the uterus for a longer time and its color becomes dark. If you don't know how long period irregularity is normal, you can click on the link of this article.
The longer the blood stays in the uterus or vagina, the more it is exposed to oxidation and instead of bright red, it changes to darker colors such as brown or even black. Although this is normal in most cases, its constant repetition may be a sign of hormonal problems or a partial blockage in the blood outflow pathway.
hormonal changes
Hormonal changes, especially fluctuations in estrogen and progesterone levels, can directly affect the color of period blood. An abnormal increase or decrease in these hormones may cause the uterine wall to become thicker or thinner and change the color of menstrual blood. Hormonal disorders sometimes cause the color of period blood to darken with a delay in blood flow.

Infections or inflammation of the uterus, such as endometritis or pelvic inflammatory disease (PID), can change the color of period blood. In such conditions, the blood may appear dark brown, gray, or even have an unpleasant odor. This color change is usually due to the presence of dead cells, bacteria or abnormal secretions in the menstrual blood.In many cases, infection is a side effect of washing the vagina during menstruation. During this period, do not use perfumed and strong detergents to wash the genital area.
Using drugs or contraceptive methods
Using hormonal pills or emergency pills for quick periods may affect the color of period blood. The use of contraceptive methods such as the pill, IUD or implants also affect the color of period blood. By changing the body's hormonal balance, these methods cause the color of menstrual blood to change to pink, brown, or even much darker than usual.
Nutrition and lifestyle
Nutrition and lifestyle play an important role in menstrual health and period blood color. Anemia, iron deficiency, high consumption of fast food, dehydration or strict diets can make menstrual blood lighter or darker. Also, high stress, lack of sleep and intense physical activity may disturb the hormonal balance and affect the color, intensity or timing of bleeding.
A balanced diet during the month can help improve the regularity and quality of periods.
