Occasionally no ovulation

A woman's menstrual cycle is usually 28 days long, but some may have it a few days earlier or later. Sometimes, a woman may have a "grey phase" or "white phase" in the middle of her cycle, which does not coincide with normal ovulation. In this case, the woman may not become pregnant.

Although this condition is uncommon, women still need to know how to avoid it. First, women need to stay healthy, avoid infections, and maintain healthy eating and exercise habits. Secondly, women need to pay attention to their menstrual cycles and follow their doctors' recommendations to better understand their reproductive cycles.

If women frequently miss their ovulation periods, they may need to seek help from their doctor. Doctors can assess women's health and recommend relevant examinations and treatments to ensure women's reproductive health.
