Premenstruation and ovulation are two important periods that women experience every month. For women, both periods serve important functions, such as maintaining female fertility and increasing the chance of pregnancy. In this article, we’ll discuss the basics of premenstrual and ovulation periods, and how they affect the body.

Premenstruation refers to the beginning of each month for women, when women’s reproductive organs begin to change in preparation for the next menstrual cycle. During this process, a woman's vagina will secrete a small amount of mucus, which can help lubricate the vagina and make sexual intercourse more comfortable.

The ovulation period refers to the middle of each month for women, about 14 days before menstruation. At this time, the female reproductive organs begin to secrete a large amount of mucus. This mucus can help sperm enter the uterus and increase the chance of pregnancy.

Effects on the body before menstruation and ovulation

Premenstrual and ovulation periods have many effects on the body. First, premenstrual and ovulation periods can cause changes in a woman’s reproductive organs, and these changes can affect a woman’s fertility. For example, women experience increased vaginal discharge before menstruation, which helps sperm enter the uterus. In addition, a woman's uterus also begins to contract before menstruation, which helps expel the embryo.

Secondly, before menstruation and ovulation, women's bodies will undergo changes, and these changes will affect women's health. For example, a woman's body temperature rises before menstruation, which can help predict when a woman is ovulating. In addition, women's appetite decreases before menstruation and during ovulation, which helps to maintain good health.

Finally, the period before menstruation and ovulation can also cause mood swings in women, and these changes can affect women's mental health. For example, women may experience increased mood swings before menstruation, which may lead to anxiety and depression.

To sum up, premenstruation and ovulation are two important periods that women experience every month. For women, these two periods play important roles, such as maintaining female fertility and increasing the chance of pregnancy.
