Is cramps a sign that ovulation is about to occur?

Yes, cramps, also known as mittelschmerz, can be a sign of ovulation. Ovulation occurs when a mature egg is released from one of the ovaries. The ovary that releases the egg can produce a sharp, stabbing pain or a dull ache in the lower abdomen or pelvis, usually on one side. This pain or discomfort is often referred to as ovulation pain or mittelschmerz. The pain usually lasts for a few minutes to a few hours and can also be accompanied by other symptoms, such as breast tenderness, changes in cervical mucus, and a slight increase in body temperature.
