What is mittelschmerz?

Mittelschmerz is pain or discomfort that may happen to females before, during, or after ovulation. Ovulation is when an ovary in your body releases an egg. Ovulation usually happens once a month, about 2 weeks before your period. Mittelschmerz is not serious, but it can be very uncomfortable. Mittelschmerz pain usually goes away within a few minutes to hours but may last as long as 1 or 2 days.
