It may also be caused by the fallopian tube contracting or the egg bursting from the follicle. One in five women experience pain during the time of ovulation. Typical ovulation pain occurs around the middle of your cycle—day 14 in a 28-day cycle—and lasts anywhere from a few minutes to a couple of days. It is most often felt low in the pelvis to one side, which may change each month, depending on which side the egg is released. Some people also experience nausea.

The egg bursting out of the follicle can cause the sharp, sudden pain some people feel. The pain is the result of spasms of the fallopian tubes or uterus as ovulation approaches.
