Anonymous users2024-02-06It's very simple. Let's take an analogy. If a woman has menstruation on the 2nd, then the 12th-22nd is the ovulation period, that is, the dangerous period, and the rest of the time is the menstrual period and the safe period. If you don't understand, you can continue to ask me.

Anonymous users2024-02-03On the day of menstruation in the next month, it is about 14 days forward, that is, about 16 days back in the current month's menstruation.
This is the ovulation period, and the safe period is the three or four days after the menstrual period is completely clean, which is the highest safety rate in the entire safe period.
The safe period is not counted from the menstrual period and ovulation period, and the remaining days are, but, but, but, the handover part of each period, you have to spare a day or two to count it outside the safe period, can you see?
It is recommended that you should also do a good job of contraception safety during the safe period, and tell you that there is no safer contraceptive method with a safe period than the standard contraceptive method with condoms!!

Anonymous users2024-02-02The method of calculating the safe period for women is to calculate the date of the next menstrual period, then calculate the date of ovulation, and then determine the safe period. For women with a very regular menstrual cycle, it is very easy to calculate the date of her next menstrual period.
The date of ovulation is 14 days before the date of the next menstrual period, but ovulation within two days before and after the day of ovulation (14 2) is also normal. The first 5 days and the last 4 days of ovulation are fertile periods. Days other than fertile and menstrual periods are safe periods for women.
The specific methods for calculating the safe period for women are:
Female safe period calculation method 1Extrapolation is based on menstrual cycle.
The 14th day before the menstrual date is the ovulation day, and the 4 days before the 5 days before the ovulation date is the fertile period. Safer periods are available on days other than menstrual and fertile periods.
Calculation method of female safe period, formula calculation method.
If a woman has been within the normal range for six consecutive menstrual cycles, the following formula for calculating the safe period for women can also be used:

A woman's ovulation date is generally about 14 days before her next menstrual period. Counting from the first day of the next menstrual period, the 14 days backward or subtracting 14 days is the ovulation day, and the ovulation day and the first 5 days and the next 4 days together are called ovulation. For example, if a woman's menstrual cycle is 28 days, and the first day of this menstrual period is on December 2, then the next menstrual period will be on December 30 (December 2 plus 28 days), and then subtract 14 days from December 30, then December 16 is the day of ovulation. >>>More
Your menstrual cycle is short, and the day of ovulation is closer to the first day of menstruation, on the 11th day of the cycle.
