Clotting is the body's mechanism to stop bleeding. The scab that develops on a cut is in part clotted blood that hardens to create a sort of natural bandage on the wound.
While clots in menstrual blood aren't exactly scabs, they're usually nothing to worry about. Here's how normal clots and clumps in your period form, what they're made up of, and how to know when clots may be a sign that something could be wrong. Your menstrual period starts when hormones trigger your body to start shedding the uterine lining, exposing small blood vessels and causing them to bleed.
While this blood is waiting in your uterus to pass through the cervix and vagina during menstruation, your body produces anticoagulants to help break the blood and tissue down so you can pass it more easily.
When the blood is moving faster than the anticoagulants can be produced, however, clots can form. Mixed into menstrual blood are also tiny bits of tissue from the small vessels in the lining of the uterus, the endometrium. Sometimes what appears to be a blood clot is actually a clump of endometrial cells or it can be a mixture of them and blood clots.
Dark red or blackish clots may appear during the first few days of your period when the flow is heaviest. Generally speaking, if the clots are smaller than a quarter and there is not a lot of them, you shouldn't worry. When your menstrual flow is heavier, blood clots tend to be bigger because there's a larger amount of blood sitting in the uterus. This also explains in part why, if you have a heavy flow, you're more likely to have cramping.
In order to pass larger blood clots, the cervix has to dilate a bit, causing pain that can be quite intense. If you're pregnant and are passing clots, see your doctor or go to the nearest emergency room as this may be a sign of a miscarriage or a potentially life-threatening ectopic pregnancy in which the fetus has implanted outside of the uterus.
Blood clots in and of themselves aren't a medical condition or disease but rather a possible symptom of another underlying condition.
