Some women get a one-sided pain in their lower abdomen when they ovulate.

Also known as mittelschmerz (German for "middle pain" or "pain in the middle of the month") it happens about 14 days before your period when an ovary releases an egg as part of the menstrual cycle.

Ovulation pain is often normal and just another side effect linked with menstruation .
