Can I menstruate without ovulating?

In the medical world, menstruation happens when an egg that's released from your ovary isn’t fertilized, so the uterus sheds its lining. Because of this, you cannot technically menstruate without ovulating.

However, you can still bleed — experience a “period” — without ovulating. This is known as abnormal uterine bleeding (AUB), or anovulatory bleeding. AUB is non-cyclic uterine bleeding that is irregular. Abnormal uterine bleeding is common — approximately one-third of people who have a uterus and are of child-bearing age experience it.
