Blood clots that appear when you are not having your period can be caused by a range of issues. But since some of them can be serious—including uterine fibroids, endometriosis, bleeding disorders, miscarriage, and cancer—it's best to see a healthcare provider.
You might pass large shiny red clots that look like liver as well as other pieces of tissue that look and feel like membrane. It might be painful and feel just like labour, and you might need pain relief in hospital.
Endometriosis blood clots may appear as dark or bright red clumps or blobs in menstrual flow. The clots can vary in size and texture, ranging from small and grainy to larger and more jelly-like in consistency.
A decidual cast is usually red or pink. It's made up of tissue, mucus and blood and looks “fleshy” like a piece of raw red meat. It may look similar to a clot you'd see during your period, except it's much larger and has a slightly different texture. It's shaped like your uterine cavity, which resembles a light bulb.
Color: Menstrual bleeding is typically a bright to dark red, and will look like what you typically experience during your monthly period. Implantation bleeding is a much lighter hue, typically a very light pink or light rust color.
Here are some differentiating factors: Miscarriage bleeding is generally heavier and lasts longer than your period. During a miscarriage, you might notice fetal tissue and large blood clots. Miscarriage blood might be a different color than your period; it generally presents as pink, red, or brown.
Bleeding that occurs during a miscarriage doesn't always look the same. It can be light pink or red, brown or black and grainy, or even look just like a normal period.
Implantation bleeding
You may experience light pink or brown spotting after a positive pregnancy test. This could be due to implantation bleeding, which occurs when a fertilized egg implants in the lining of the uterus, one to two weeks after conception.
Implantation bleeding may initially resemble the start of a menstrual period. However, while menstrual flow will usually get progressively heavier, implantation bleeding will not. On a pad: Implantation bleeding is usually light and, therefore, should not soak a pad.
In early pregnancy, you might get some harmless light bleeding, called "spotting". This is when the developing embryo plants itself in the wall of your womb. This type of bleeding often happens around the time your period would have been due.
With endometriosis, the endometrial-like tissue acts as endometrial tissue would — it thickens, breaks down and bleeds with each menstrual cycle. But because this tissue has no way to exit your body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form.
If your period feels stuck or doesn't seem to be coming out, it could be due to hormonal changes or from some type of obstruction. If your period feels unusual or different than normal, it's best to contact a gynecologist for an evaluation.
Blood loss during an implantation bleed tends to be light or described as “spotting”. It is mostly pinkish and watery in appearance, though it may also be a brighter red colour or even brown. After lying down for a while or first thing in the morning, the blood may be more of a brownish colour.
Implantation bleeding is:
Does not contain blood clots or tissue. Not enough to fill a pad or tampon; most people only notice a small amount of implantation spotting on their underwear or when they wipe.
If you've had bleeding early in your pregnancy, you're not alone. Many other pregnant women have early bleeding, too. And in most cases, nothing is wrong.
You can't have your menstrual period while pregnant, although some women do have vaginal bleeding during pregnancy. Some even report intermittent bleeding that seems like a regular period to them. But vaginal bleeding during pregnancy is not the same thing as menstruation.
While pregnancy does sometimes come with light bleeding or spotting, the truth is that you cannot be pregnant and still have a period.
What does miscarriage tissue look like? If the miscarriage happens in the first six weeks of pregnancy, tissue is quite microscopic, so the vaginal discharge will be similar to a heavy period. You might pass the odd medium size blood clot but there are no really noticeable differences from your menstruation.
