Retrograde menstruation is when menstrual blood flows backward instead of out of the body. Instead of leaving the body through the vagina, the blood moves backwards into the pelvic area. This backward flow carries blood and tissue into the fallopian tubes and other parts of the pelvis.

While many women have some backward flow during their period, most don't notice it. But for others, it may lead to pain, swelling, or a condition called endometriosis. This is why it's important to know about it.

What Are the Symptoms of Retrograde Menstruation?

Most women with retrograde menstruation do not have clear symptoms. But when the backward-flowing blood causes problems, certain signs can appear. These symptoms are sometimes confused with normal period pain.

Some possible signs include

What Causes Retrograde Menstruation?

Doctors are not sure what exactly causes retrograde menstruation. However, they believe several things might increase your chances of having it.

These include:

Some people also ask if using menstrual cups can cause this. There's no proof yet, but it's being studied.

How Is It Linked to Endometriosis?

Retrograde menstruation is one of the top theories behind endometriosis. This happens when tissue that's supposed to grow inside the uterus starts growing outside of it. These tissues may stick to organs like the ovaries, bladder, or bowel.

When this tissue bleeds each month, it can't leave the body. Instead, it stays trapped and causes swelling, pain, or scarring. Not everyone with retrograde menstruation will get endometriosis, but many women with endometriosis also have retrograde flow.

How Is Retrograde Menstruation Diagnosed?

There's no simple test to show retrograde menstruation. Most people find out they may have it when they see a doctor for other issues like pelvic pain or infertility. Doctors usually check for signs of endometriosis or tissue buildup.

Diagnosis is often based on symptoms, history, and test results together.
