What is the safety period, and how long is the safety period?

It depends on how many days your period is usually and whether the duration of your period is stable.

The general safety period is seven days after the menstrual period is cleaned, eight days before the menstrual period, and the middle few days are the ovulation period, which is the best time to conceive. However, depending on the length of the individual's menstrual period, it may be added or decreased. At the same time, it is best to have a relatively stable menstrual period (there is a certain record of menstruation), otherwise menstrual disorders are easy to calculate failure, and the duration of each menstrual period will vary by a few days, so it is generally necessary to subtract a few days if you want to be absolutely safe.

But this is not insurance, like your situation does not know how many days your menstruation is general, if the menstrual period is stable, the menstrual period is short, and it is about to enter the ovulation period, the probability is relatively large; If you have a longer period, it should still be a safe period.

The general safe period refers to the first 7 days and the last 8 days of menstruation, but the specific also varies from person to person, if the recent menstrual period is irregular or something, then her safe period is not so accurate, and the safe period is only a small chance of pregnancy, but it is not 100% not pregnant. Some people are easier to conceive, but you are not necessarily one of the few. It is recommended to take a contraceptive pill to rest assured.

The safest thing to say is that the first five and the last five. That is, the first five days of menstruation and the last five days after menstruation. I don't want to say more, friends are cautious!

On average, a month is 4 weeks, assuming the first week is the menstrual period, then the third week is almost the ovulation period, that is, the danger period, and the middle two weeks are the safe period. Of course, it may actually be a day or two off. But that's pretty much it, and if you have those days of your period every month, you'll have no problem.

An extra sentence: emergency contraceptive pills can't be taken more, *** is huge. Or insist on taking safety measures.

There is no such day as a certain 100% safe period.

Take birth control pills when you are pregnant.

Menstrual cycles can be long and short, but the interval between the day of ovulation and the start of the next menstrual period is relatively fixed, usually around 14 days. The calculation method is calculated from the first day of the next menstrual period, and the 14 days backward or subtracted 14 days is the ovulation day, and the ovulation day and the first 5 days and the last 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.

Ovulation is the day of ovulation and the 5 days before and 4 days after, that is, from December 11 to 20. In addition, in the menstrual cycle, except for the menstrual period and ovulation period, the rest of the time is the safe period, so in the menstrual cycle, there is a pre-ovulation safe period and a post-ovulation safe period. In fact, this is also the theoretical basis of the rhythm contraceptive method.

However, to calculate the ovulation period with this method, we must first know the length of the menstrual cycle, so as to calculate the accurate time of the next menstrual cramp, and then to calculate the ovulation period, so this method can only be applied to women who have always had a normal menstrual cycle. For women with irregular menstrual cycles, it is impossible to calculate the date of the next menstrual period. Therefore, it is not possible to calculate the date and period of ovulation.

The safe period is commonly known as the first seven and the last eight, which is divided into the pre-ovulation safety period and the post-ovulation safety period. The period from the day of menstruation to the day before the start of ovulation is the safe period before ovulation. The safe period after ovulation is from the first day after ovulation ends to the day before the next menstrual period.

It is safer after ovulation than before ovulation.

The first three and the last four. It's not completely safe, though. If it is a couple who are in love, it is recommended that the man take safety measures.
