How is the safe and dangerous period calculated?

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. The principle is that there is no conception after the egg is released, and menstruation is fixed after 14 days. Since your cycle is shorter, it means that the time spent before ovulation is shorter.

5 to 4 days before ovulation is the dangerous period, and other safety. Your situation is the danger period from the 6th day of the cycle to the 14th day. The security period is further divided into a relative safety period and an absolute safety period.

There is only an absolute safety period when no measures need to be taken.

If you want to get pregnant, the 8th and 14th of the cycle is the best time to conceive.

Cycles all start on the first day of menstruation. Menstruation is usually 4 to 5 days, according to 5 days, the first day after cleaning is the 6th day of the cycle, which is already a dangerous period. There is no safe period after menstruation is clean.

We usually calculate the absolute safe period, which is calculated on a scale from 7 days before the ovulation date to 7 days after the end of the month.

Let's say your cycle is 25 27 days, and you push the time of your next period by 27 days, and count 7 days forward to the safe period. For example, if you have your period on November 1st, your next menstrual period will come on November 28th at the latest, and the 28th, 27th, 27th, 25th, 24th, 23rd, 22nd, and 21st are safe periods.

Generally, 7 to 10 days after menstruation is clean, ovulation is also a dangerous period, and the day of non-ovulation is a safe period.

But this doesn't apply to everyone, because everyone's constitution is different, and the ovulation period is different, and it needs to be combined with the analysis of menstrual regularity.

Why not wear a condom that is safe and hygienic.

It's simple to wear a sleeve, safe and hygienic.

For women with regular menstruation, it is generally a safe period except for the ovulation period (that is, 14 days before the next menstrual period is the ovulation day, and 4 days before and 3 days after the ovulation preparation date is the ovulation period); If Yan Chi is a woman with irregular menstruation, there may be ovulation disorders, and the ovulation time is not fixed, so it is difficult to calculate the safe period.

The mantra of the first seven and eight after the safe period is not quite you. Because your short cycle has 26 days, ovulation occurs on the 12th day of the cycle, and the danger period begins on the 5th day of the cycle, 7 days before the ovulation date. The 26th, 26th, 27th, 28th, and 29th are the safe periods, and the menstrual period is clean and the dangerous period begins.

In a 26-day cycle, the next menstrual period is November 21st, and the ovulation day is November 7th;

In a 30-day cycle, the next menstrual period is on November 25th, and the ovulation day is November 11th;

Seven days before and seven days before ovulation is the danger period. The safe period is October 26, 27, 28, 29 and November 25, 24, 23, 22, 21, 20, 19. In short, the shortest cycle (26 days) is followed by postmenopausal (pre-ovulation) and the longest cycle (30 days) is followed by a premenopausal (post-ovulation) safe period.

Ovulation is most likely to occur on any day from November 7th to 11th, and the best time to conceive is November 4 and November 14th. Other times the probability of pregnancy is low, but it is possible.

Pregnancy is most likely to occur on the 8th to 19th of each month.

The safety period is generally the first seven and the last eight, but it is not absolute, it is best to take safety measures, and it is not recommended to take medicine.
