It's perfectly normal to notice some clumps from time to time during your period. These are blood clots that may contain tissue. As the uterus sheds its lining, this tissue leaves the body as a natural part of the menstrual cycle. So clots of tissue are usually nothing to be concerned about.
Polyps and Fibroids
Uterine polyps that grow on the cervix or in the lining of the uterus can also be a factor in heavy clotting. If you're experiencing heavy bleeding, large blood clots during your period or lower back pain, it could be a uterine obstruction like a fibroid.
Passing blood clots during menstruation can be normal. The amount, length and frequency of menstrual bleeding vary from month to month and from woman to woman. However, passing large blood clots may be a sign that something's wrong.
Menstrual clots resemble pieces of mashed-up red fruit. They can be bright red or burgundy and may vary in size. They are usually mixed with liquid blood. The longer the blood stays inside the uterus, the darker it is in color, and the likelier it is to form clots.
Each month, the endometrial tissue inside your uterus thickens. After ovulation, if you don't become pregnant, the endometrial tissue sheds and bleeds in a process known as menstruation. With endometriosis tissue, the same thing happens, causing pain and inflammation in the areas with endometriosis outside the uterus.
A decidual cast is a large, intact piece of tissue that you pass through your vagina in one solid piece. It happens when the thick mucus lining of the uterus, called the decidua, sheds in the near exact shape of your uterine cavity, creating a triangular “cast.”

The tissue you pass may look dark red and shiny — some women describe it as looking like liver. You might find a sac with an embryo inside, about the size of a small bean. If you look closely, you might be able to see where the eyes, arms and legs were forming.
It can be light pink or red, brown or black and grainy, or even look just like a normal period. If the loss occurs early in your pregnancy, there may be minimal clotting, but the farther the pregnancy has progressed, clots might be denser and larger and you might notice tissue that you don't normally see with a period.
You know how long and heavy your typical period is. During a miscarriage, bleeding gets heavier and lasts longer than a period. As your cervix starts to dilate, cramping may become more painful than typical period cramping.
How do you know if you have heavy bleeding? If you need to change your tampon or pad after less than 2 hours or you pass clots the size of a quarter or larger, that is heavy bleeding. If you have this type of bleeding, you should see a doctor.
It is believed that fibroids don't allow the uterus to contract properly, so it's unable to effectively stop menstrual bleeding. Another issue is fibroids produce growth factors (proteins) that stimulate the blood vessels of the uterus and cause more blood in the uterine cavity, leading to heavy periods at night.
Changing your pad every 3 or 4 hours (more if your period is heavy) is good hygiene and helps prevent bad odors. This is especially true if you'll be playing sports or rushing around from class to class. Changing pads often also helps prevent accidental leaks.
Passing blood clots or a sudden gush of blood when you're not on your period is common among people with a menstrual cycle. They can be caused by hormonal changes from menopause or polycystic ovary syndrome (PCOS), uterine growths, or thyroid issues. Clots are most common when period blood is at its heaviest.
The term refers to a pregnancy in which there is some level of bleeding, but the cervix remains closed and the ultrasound shows that the baby's heart is still beating.
Often, a woman can have an extra heavy menstrual flow and not realize it's a miscarriage because she hadn't known she was pregnant. Some women who miscarry have cramping, spotting, heavier bleeding, abdominal pain, pelvic pain, weakness, or back pain.
Bleeding during miscarriage can appear brown and resemble coffee grounds. Or it can be pink to bright red. It can alternate between light and heavy or even stop temporarily before starting up again. If you miscarry before you're eight weeks pregnant, it might look the same as a heavy period.
As your period continues, you may notice blood that's jelly-like or broken up into thick clumps. This is typically caused by blood clots that are passing through your body. This is normal during any part of your period.
When it's expelled, a decidual cast will be red or pink. It will be somewhat triangular and close to the size of your uterus. This is because the entire lining of the uterus exited as one piece. The decidual cast will also appear fleshy because it's made up of tissue.
If the person does not become pregnant, the endometrial lining is shed during the menstrual period. With menopause, ovarian hormone production largely stops and the lining stops growing and shedding.
Each month, as part of the menstrual cycle, the body prepares the endometrium to host an embryo. Endometrial thickness increases and decreases during the process. Two hormones, estrogen and progesterone, prompt these cycles of endometrial growth and its shedding through menstruation if a pregnancy does not develop.
Endometriosis can affect women across all ethnic backgrounds and at any age, but it most commonly affects women during their reproductive years between the ages of 25 and 35.
Retrograde menstrual flow is the most likely cause of endometriosis. Some of the tissue shed during the period flows through the fallopian tube into other areas of the body, such as the pelvis. Genetic factors. Because endometriosis runs in families, it may be inherited in the genes.
