Menstrual Blood Color

Menstrual Blood

Menstruation and general health are intricately connected, and the patterns of a woman’s period can provide us with important information about their well-being. From the duration of the menstrual cycle, to its intensity and blood color, we can usually understand if our bodies are healthy or if something is off and requires further investigation. Though the absence or presence of periods is what usually alerts us to possible problems, the menstrual blood color can be an indicator of possible problems, as health conditions and hormonal changes affect the color and texture of period blood.

Different Colors of Menstrual Blood:

Bright Red

  • We usually associate red blood with a normal period flow, and most of the times this is the case. Menstrual blood that is red is fresh blood, and at the start of the period it is this color; for some it remains red, while for others it turns brown in the later days of their period. However, bright red blood in between periods or when you do not expect it might indicate the presence of an STI or be cause for concern for other health issues associated with your uterine lining or cervix. Particular attention should be paid if that is combined with a heavy flow and longer periods, abnormal weight loss and pain in the lower back.

Dark Red or Brown

  • Darker blood is not an immediate cause for concern, as many myths will have us believe. In reality, it is oxidized blood—or old blood—that has been in the uterus longer. It may appear at the beginning of a period as a remnant of the previous cycle, or at the end of a period as blood that had time to oxidize. The older the blood that is being discharged, the darker it will be: even if it appears closer to black, there is no cause for concern. If you are, however, experiencing abnormal symptoms on your own body, consult your doctor.

Black

  • Like dark red or brown, black blood is old blood that has remained in the uterus a long time and has oxidized. As discussed above, it is no cause for concern as the sole symptom, though sometimes it may be a sign of a blockage inside the vagina. If that is the case, other symptoms of a blockage may include itching or swelling in the vaginal area, difficulty urinating, fever and foul-smelling discharge.

Remember that it is normal for your period blood to change colors in the duration of your period, as it does not always start from fresh blood. There may be old blood and uterine lining that needs to be shed, and that also usually results in blood clots or other discharge. If you suspect that the color of your period blood may be indicating a health issue for you, or you are experiencing concerning health symptoms during your period, always consult your healthcare provider or a health expert.
