Mittelschmerz

Mittelschmerz is a funny way of saying "middle pain" in German. It is when some girls and women who have periods feel a little bit of pain or discomfort in their lower belly, usually around the middle part of their cycle.

When a girl's body is getting ready for her period, she releases an egg from an ovary. Sometimes, when the egg is getting ready to be released, it can cause a little bit of pain or cramping in the lower belly, and this is called Mittelschmerz.

It's nothing to worry about, and it usually goes away on its own after a little while. If someone gets really bad Mittelschmerz or if it happens every month, they can talk to a grown-up doctor about it.
