Pain during ovulation is called Mittelschmerz - literally, "middle pain". Having a bit of pain mid-cycle is pretty normal, although if it's so serious it interferes with your day, it might indicate there's something wrong and you need to see a doctor. Here's why many of us feel pain at ovulation...

Sometimes Mittelschmerz is experienced as a short, sharp burst of pain. When this happens, it's because the ovarian follicle doesn't come with a handy escape hatch for the egg. Instead, the egg just fucking bursts out of there like the Kool-Aid man.

Pain from the egg bursting out is pretty short-lived, though can be quite intense. Sometimes you might experience the pain as definitively to one side or the other, depending on which ovary.

And sometimes Mittelschmerz is experienced more as a duller pain that goes on for a few hours. You might imagine that the egg just whizzes down the uterine tube like a helter-skelter. This is not, in fact, how it works. The tube squeezes that egg down like a tube of toothpaste.

It's this squeezing action (peristalsis) which might be experienced as the dull, aching pain around ovulation.

If we look at a real ovary and tube, we can see some signs of all this action going on. First, if we look at the surface of the ovary (the rounded, paler part), we can see little scars all over the surface. Each little scar is caused by an egg bursting out of there.
@vagina_museum this is bullshit. Someone should redesign this. Worst part of the human design. It shouldn't be nearly that dramatic just to lay an absolutely microscopic egg. 0/10 for the yeeterus.
