2. How to calculate the menstrual cycle

The menstrual cycle, also called the ovarian cycle, is divided into four phases, including the follicular phase, ovulation phase, luteal phase, and menstruation phase:

1. Follicular phase: The follicular phase is from the first day of menstruation to the day of ovulation. During this period, under the influence of follicle-stimulating hormone, the concentration of estrogen in the body increases, the follicles gradually mature, and the endometrium thickens.

2. Ovulation period: Ovulation period refers to the process in which the egg cell and the surrounding cumulus granulosa cells are discharged together. A woman's ovulation date is generally about 14 days before the next menstrual period.

3. Luteal phase: The luteal phase refers to the period from ovulation to the day before menstruation. The ovaries are affected by luteinizing hormone and secrete progesterone to maintain the thickened endometrium to facilitate the implantation of the fertilized egg. If the fertilized egg does not implant, the endometrium will collapse and the menstrual cycle ends with the onset of menstruation.

4. Menstrual period: The duration of each menstrual period is called the menstrual period, which is generally 2-8 days, with an average of 4-6 days. Generally, there are no special symptoms during menstruation, but due to pelvic congestion and the effects of prostaglandins, some women may experience discomfort in the lower abdomen and lumbosacral area or uterine contraction pain, and may also experience symptoms of gastrointestinal dysfunction such as diarrhea.
