The luteal phase is the day of the menstrual cycle

Although many women start to have their periods at a certain age, they do not have a comprehensive understanding of many knowledge related to menstruation. It is very important for women to have their periods. If you are not careful, it may cause physical discomfort. There is a follicular phase before and after menstruation. Now let's find out together, which day of the menstrual period is the follicular phase?

How many days does the follicular phase last?

The follicular phase generally refers to the 15th to 28th day of the menstrual cycle, which usually lasts for 14 days. At this time, the uterus and ovaries are fully developed, and lutein is slowly produced during the ovulation period, which is called the follicular phase. For example, if a woman's menstrual cycle is 28 days, then the first 14 days are the follicular phase, and the last 14 days are her ovulatory phase.

From the ovulation period to the day before the menarche, the uterus and ovaries are affected by luteinizing hormone, which metabolizes luteinizing hormone to maintain the thickened uterine wall to facilitate the combination of sperm and egg and implantation. If there is no sperm and egg, the uterine wall will dissolve and the physiological cycle ends with the menarche.

During the follicular phase, under the synergistic effect of estrogen and estradiol, the uterine wall further proliferates, blood vessels grow, and the glandular ducts begin to secrete mucus containing glycogen. At the end of this period, the growth of the uterine wall reaches its peak, preparing the conditions for the implantation and continued growth of the sperm and egg.

In the early follicular phase, women's physical and mental states are still in a relatively stable state. They will not feel extremely positive or negative. But as this cycle comes to an end, estrogen gradually increases and begins to produce effects, and the woman's physical condition will begin to become increasingly unstable. The last few days are when women are at their lowest point in their mood, prone to mood swings, irritability, anxiety, and mood swings. Therefore, women's temperament is generally very bad in the early stages of menstruation. Skin problems also started to appear: skin became rough and acne broke out.
