How many days does a woman have a safe period in a month?

The commonly used methods for estimating the "ovulation period" are: 1. Cervical mucus observation method (must be done in the hospital). 2. Basal body temperature measurement.

That is: the body temperature measured after waking up after a long period of sleep (usually in the early morning), before any activity and speech, is the basal body temperature. Normally, the basal body temperature of women of childbearing age is lower in the first half of menstruation and lower during ovulation, and can rise suddenly or slowly within a few days 24 hours after ovulation.

Therefore, it is best to measure basal body temperature from the first day of menstruation, insist on daily measurement, and record it with coordinate paper for observation and analysis. 3. Calculation of the date of passage. Both:

It is believed that each ovulation should be about 14 days before the onset of menstruation, so the 5 days before ovulation - 5 days after ovulation is called the "ovulation period". However, this method is less reliable because most women do not menstruate so regularly. In contrast, the first two methods are more reliable, but somewhat cumbersome.

Here we introduce you to a simple and reliable estimation method, which we hope will be helpful to you. The calculation formula is: the first day of ovulation The number of days of the shortest menstrual cycle minus 18 days The last day of ovulation The number of days of the longest menstrual cycle minus 11 days Before using this formula to calculate, I am required to observe and record my menstrual cycle for 8 consecutive times to obtain the longest and shortest days of my menstrual cycle, and the numbers obtained by substituting the above formula represent the beginning and end of the woman's "ovulation" respectively.

The calculation of the menstrual cycle is from the first day of the menstrual cramp to the first day of the next menstrual cramp) For example: the menstrual cycle of a woman of childbearing age in the first 8 months is the longest 30 days, and the shortest is 28 days, and the substitution formula is: The first day of ovulation 28 days - 18 days 10 days The last day of ovulation 30 days - 11 days 19 days, namely:

The woman's "ovulation period" begins on the 10th day of the current menstrual period and ends on the 19th day of the current menstrual period. If you observe that your menstrual period is regular every 28 days, then you can set the maximum number of days and the shortest number of days in your menstrual cycle at 28 days, and substitute the formula to calculate your "ovulation period" as:

The 10th-17th day of menstruation. This calculation method is based on the first day of the menstrual cramps, and the number of days is counted backwards, rather than the next menstrual cramp as the base point, and the number of days is counted backwards, so it is not easy to get the third day after the end is the safe period.

The days you said above are safe, you know according to my calculations, from the first day of menstruation to the 15th day, this is the safe period, and the period between the 20th day and the next menstrual period is the safe period, that is, the 15th to 2nd and 20th days of menstruation are dangerous periods, understand?

The first seven and the last eight refer to the safe period for the seven days before menstruation and eight days after menstruation, which refers to the relative people with normal menstrual cycles, and it is not safe for people who are not very accurate in menstrual cycles.

It's useless to say that much, and the safe period is not the safest, with a 1 to 22 percent chance of failure, and the relatively safe ones are 1 to 3 days before menstruation and one to 2 days after menstruation, provided that the period is accurate.

Be aware that contraception is a safe period every day! You should cherish your body, don't be old, abortion has a lot of sequelae and affects the chance of pregnancy in the future.

The safe period is a menstrual cycle in addition to the menstrual period and the first three and four days of the ovulation period (more insurance on the first four and the last five), the safe period is not the most reliable contraceptive method, guidance: the menstrual cycle is regular, each cycle is 28-30 days, ovulation is generally about 14 days before the next menstrual period, and within 10 days between 5 days before ovulation and 4 days after ovulation, it is also a fertile period.

According to the memory of the first 7 and 8 after the beginning, it is basically an absolute safe period within 7 days before a woman's menstruation and 8 days after the start of menstruation

The simplest algorithm of the first 7 and last 8 is the first 7 days of bleeding and the last 8 days after the end.

If you do it, you will know, and if you are afraid, you can wear a condom.

What exactly is the safe period? **The doctor teaches you how to calculate, hurry up and learn it.

The day of the last menstrual period + 15 days is the ovulation period, and the time outside the first 4 days and the last 5 days can be said to be the safe period, that is:

Days other than the 11th to 20th day of the last menstrual period are safe periods.

However, the safe period is not necessarily safe, and the probability of contraception is up to 60%, and the safety degree can be up to 99% with condoms.

In the case of regular menstrual cycles; The first seven days of menstruation and the last eight days of menstruation are absolutely safe periods!

Three days before menstruation Four days after menstruation ends.

The week before and after menstruation is a safe period.

The safe period is the first 7 days and the last 8 days of menstruation.

As long as the ml is left, the woman may be pregnant before seven and eight after the eight, not every time. It can only be said that the possibility of conceiving 7 days before menstruation or 8 days after menstruation is very, very small. But it's not necessarily that you won't be pregnant ...

Please, as long as you do it, it's possible to conceive the first seven and the last eight is not accurate every time. It can only be said that the possibility of pregnancy 7 days before or 8 days after menstruation is very, very small. But it's not necessarily that you won't be pregnant ...

Haha, condoms are king.

It seems to be 5-10 days after menstruation.

The next menstrual period is reduced by 14 days and 5 days before and after, it is easy to get pregnant, and the others are safe.

There is no such thing as absolute security unless you don't do that.

Came the week before the great aunt.

It is safe for the first five days and the last six days of the menstrual period.

The menstrual cycle is normal, the first seven and eight days of menstruation are the safe period, and the middle eight to ten days is the dangerous period, but the safe period is not necessarily safe, so it is best to choose other contraceptive methods.

Seven days before the great aunt comes, eight days after the cleansing, these fifteen days are the safe period, and then the 3-5 days when the great aunt is there, and the rest is the danger period.
