How to calculate menstrual cycle
The calculation of menstrual cycle is usually done on the first day of menstrual bleeding, which is the beginning of the menstrual cycle. The interval between the first day of the next menstrual cycle is called the menstrual cycle, and the number of days between is called the number of days in the menstrual cycle. It is generally between 21 and 35 days, with an average of 28 days. If the current month's menstrual cycle starts from 5 days, the next month's 5 days are 30 days, and the number of days in the menstrual cycle is 30 days. A menstrual cycle of less than 21 days is called frequent menstruation, and a menstrual cycle of more than 35 days is called sparse menstruation. Changes in the menstrual cycle require relevant examinations, which may be caused by diseases.
What's wrong with menstruation being earlier than one month
If menstruation is advanced by one month, the menstrual cycle is shortened. The most common reasons are as follows: 1. Due to insufficient luteal function, endocrine disorders, and premature atrophy of the corpus luteum, the clinical manifestation is a shortened menstrual cycle. This situation can also lead to infertility and should be actively treated. 2. It is caused by fibroids under the uterine mucosa. Due to the growth of submucosal fibroids in the uterine cavity, the area of the endometrium is relatively increased, and protruding fibroids in the uterus can affect uterine contraction. Clinically, it can lead to shortened and prolonged menstrual cycles, but it can also manifest as an increase in menstrual volume. Therefore, it is recommended to undergo six sex hormone tests on the second or third day of menstruation. In addition, when B-ultrasound examination is needed, it is recommended to draw blood to check blood routine and clotting time to exclude premature menstruation caused by thrombocytopenia or coagulation dysfunction.
The menstrual cycle, also known as the ovarian cycle, is divided into the follicular phase before ovulation and the luteal phase after ovulation. Then the menstrual cycle can be divided into four stages, including follicular phase, ovulation phase, luteal phase, and menstrual phase. More accurate calculation. The following menstrual cycle is calculated based on 28 to 30 days.
The follicular phase occurs on the 5th to 14th day of the menstrual cycle, from the 5th day to the day of ovulation. During this period, under the influence of filtering hormone, the estrogen level in the body significantly increases, the follicles gradually mature, and the endometrium thickens.
Ovulation period refers to the process of egg cell maturation and expulsion. The ovulation day for women is generally 14-16 days before the next menstrual cycle, with ovulation days and their first 5 and last 4 days as the ovulation period, and the rest of the time as the safe period.
