Ovulation pain (mittelschmerz): what it feels like

What ovulation pain feels like

Ovulation pain — sometimes called mittelschmerz, German for 'middle pain' — is a one-sided lower abdominal or pelvic pain that happens around ovulation, roughly mid-cycle. It can feel like a dull ache, a sharp twinge, or a cramp, and it usually lasts anywhere from a few minutes to a day or two.

It typically switches sides from month to month, depending on which ovary releases the egg. Some women get it most cycles; many never notice it at all.

Why it happens

The pain is thought to come from the growing follicle stretching the ovary surface, and from the small amount of fluid or blood released when the egg bursts out, which can irritate the surrounding area. It's a normal part of ovulation and can be a useful sign of your fertile window.

Some women also notice light spotting or a change in discharge around the same time, which is also normal.

When to get pain checked

Mild, brief, mid-cycle pain is usually nothing to worry about. But see a GP if the pain is severe, lasts more than a couple of days, is getting worse over time, or comes with fever, heavy bleeding, pain during sex, or pain that isn't clearly cyclical — these can point to conditions like ovarian cysts, endometriosis or infection.

If pelvic pain is a regular problem for you, it deserves proper assessment. A telehealth consult can start that and arrange any scans or tests needed.
