Ovulation does not come

First, some women may be affected by hormonal levels. Around puberty, a woman's hormone levels change, which can lead to irregular ovulation. In addition, some women may be affected by factors such as medications, disease, malnutrition, or excessive stress, resulting in irregular ovulation.

Second, some women may be affected by surgery or family planning techniques. For example, family planning surgery may cause irregular ovulation because the surgery may affect a woman's hormone levels.

Finally, some women may be affected by psychological stress. Psychological stress may cause changes in a woman's hormone levels, leading to irregular ovulation.
