Is it negative even if the ovulation period has not passed? ——Discover the mystery of women’s menstrual cycle

However, for many women, their menstrual cycles are irregular or they miss the peak period, which may lead to poor egg release and thus affect women's fertility. In this case, some women may choose to use medications to regulate their menstrual cycles or use other methods to promote egg release.

So, why do some women fail to ovulate? This can be due to a number of factors, including:

1. Irregular menstruation: Irregular menstruation refers to irregular menstrual cycles in women, which may affect a woman’s fertility.

2. Disease: Certain diseases, such as ovarian disease, uterine disease, and vaginal disease, may cause women to miss their peak period, thereby affecting their fertility.

3. Medications: Certain medications, such as hormonal medications, may affect a woman's menstrual cycle, causing them to miss their peak period.

4. Other factors: such as diet, exercise and stress, can also affect a woman's menstrual cycle, causing them to miss their peak period.

So, how do women determine their ovulation period? Generally speaking, women can determine their ovulation period through the following methods:

1. Observe your own body temperature: Women can determine their ovulation period by measuring their basal body temperature. Generally speaking, during a woman's menstrual cycle, her basal body temperature will change, especially when her body temperature rises, which may mean that a woman is about to enter the ovulation period.

2. Observe your own sexual desire: A woman’s sexual desire will also change during her menstrual cycle. Generally speaking, during women's ovulation period, they feel more aroused and sensitive, which may affect their sexual desire.

3. Observe your own appetite: Women’s appetite will also change during the menstrual cycle. Generally speaking, during women's ovulation period, they feel hungrier, which may affect their appetite.

To sum up, it is not easy for women to determine their ovulation period. However, by using the above methods, women can better understand their bodies and gain better control over their menstrual cycles. If women do not ovulate, they can take some steps to adjust their cycles to improve their fertility.
