What does it mean if you have cramps on a high fertility day?

Cramps on a high fertility day may indicate that ovulation is approaching or occurring, as some women experience mild cramping due to the release of an egg from the ovary. This is often referred to as mittelschmerz, or ovulation pain. However, cramping can also result from other factors, such as hormonal changes or premenstrual symptoms. If the cramps are severe or concerning, it's advisable to consult a healthcare provider.
