The day from the first day of menstruation is the ovulation period

A perfect egg is released in every normal menstrual cycle of a woman, and the day when the egg is released is the ovulation period. The ovulation period refers to the 4-5 days before and after ovulation, about seven days.

The follicular phase of the ovary during the physiological cycle is relatively stable, generally lasting 14 days. The duration of the follicular phase of the uterus and ovaries during the physiological cycle is generally uncertain, so the ovulation period generally needs to be estimated based on the follicular phase. If it is calculated from the first day of the due date of pregnancy in the follicular phase, there will be a large deviation from the first day of the due date of pregnancy due to the different lengths of the menstrual cycles of different people. Calculating 14 days from the first day of menarche is relatively stable and reliable. Therefore, the 14 days before the next menarche is calculated as the ovulation period, and the 4-5 days before and after the ovulation period is the ovulation period.

You must drink enough water every day to promote basal metabolism and reduce the growth of urethral bacteria. If you secrete a lot, please change your sanitary napkin frequently to ensure that your underwear is clean and tidy. Women who have not yet planned to have children should pay attention to taking contraceptive measures during the ovulation period. It is recommended to use condoms or take emergency contraception.

If the menstrual cycle is 30 days, it is counted from the first day of the menstrual period, and the ovulation time is about 16 days. Then count forward 4 days based on the ovulation time, and the next 3 days is the ovulation period. Therefore, it is recommended to calculate according to your own menstrual cycle. Basically, the ovulation period is 14 days before the next menstrual period, so it is very easy to calculate the ovulation period based on the ovulation period. In addition, if it is the case of menstrual disorders, it is impossible to calculate the time of ovulation according to the menstrual cycle, nor is it possible to calculate the ovulation period. Therefore, in this case, it is best to go to the hospital for B-ultrasound examination to understand the size of the egg. If the egg is basically good, ovulation will occur one day later, so a B-ultrasound examination is required.
