What is the period of women s safety period?

It is the 7th day before menstruation to the 8th day after menstruation.

Female ovulation is generally about 14 days before the next menstruation, and within 10 days between 5 days before ovulation and 4 days after ovulation is the ovulation period (the menstrual cycle should be more regular, each cycle is 28-30 days), also known as the female fertile period, then, the first seven days and the last eight days of menstruation (commonly known as "the first seven and eight days") is the "safe period" (can only be said to be relatively safe, because female ovulation is affected by many factors, such as taking certain drugs, endocrine disorders, irregular menstruation, mental stress, work pressure, Emotions are extremely excited, emergencies, etc.).

If the menstrual cycle is regular, ovulation is calculated as follows:

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.

If menstruation is not normal, ovulation is calculated as follows:

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.

For example, if the menstrual period is a minimum of 28 days and a maximum of 37 days, it is necessary to subtract 18 (28 18 10) from the shortest regular period and 11 (37 11 26) from the longest regular period, so the 10th to 26th days after menstrual cramps are considered ovulation. It's not a safe time when you're ovulating.

Hope it helps.

The safe period is 3-5 days before and after menstruation, which is not 100% safe, but the possibility of pregnancy is very small.

For example, if a woman has her period on the 8th, then the 18th-28th is the ovulation period, which 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.

The menstrual cycle is divided into three phases: with 28 days as the menstrual cycle, the safe period is about 1 to 14 days.

Ovulation occurs around the 14th to the 22nd.

The menstrual period is around the 22nd to the 28th.

The safe period is from one week before menstruation to one week after menstruation.

Let's wear a condom, it's a safe period 365 days a year, so enjoy it

1. If you are in good health, seven days before and eight days after menstruation.

2. Those who are infertile, all the time.

Menstruation comes seven days before and eight days after.

Menstrual period: 7 before and 8 after 8 is the safe period.

From the first day of the last menstrual period to the first day of the next menstrual period, a total of about 28 days, 14 days before and after the first day of the next menstrual period is the danger period, usually the danger period is slightly extended to one week, and then the number of days of the last menstrual period is removed, which is the safe period.

What are the safe periods? How many days before and after menstruation is a safe period? The safe period is the period of time between the end of the last ovulation and the next ovulation.

Generally speaking, if a woman takes 28 days as her normal menstrual cycle, the period of seven days before and eight days after the first day of menstruation is the safe period.

The safe period is further divided into the pre-ovulation safe period and the post-ovulation safe 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.

The post-ovulation safe period is safer than the pre-ovulation safe period. This is because some women sometimes ovulate earlier due to environmental changes and mood swings, so that the safe period before ovulation is shortened.

Seven days before menstruation and eight days after menstruation are safe periods for adult women, and are a calculation method used by most people for contraception. In addition to the calendar method, which uses the number of days calculation, there is also the basal body temperature method and the secretion observation method. However, the safe period is not absolutely safe, and sometimes a woman's ovulation will be earlier or later, and the judgment of the safe period will become invalid.

Eight days after the end of menstruation and seven days before the start of menstruation is the safe period, and the rest of the time is the dangerous period, not to mention the menstrual period
