How is the safety period calculated? Does it start on the first day of menstruation, or does it star

Hello! If you have regular menstruation, the first 3 days and the last 4 days of your menstrual period are safe periods, but safe periods are not completely safe, and effective contraception is recommended.

The safe period is calculated according to the menstrual cycle, women with normal menstruation, if the menstrual cycle is 28 days, the general ovulation is about 14 days, and the period before and after 5 days before and after the 14th day of the menstrual period is the ovulation period, and the probability of sexual conception is relatively high at this time. This period is actually a dangerous period, except for these 10 days, other times should be a safe contraceptive period, which belongs to the period when it is not easy to get pregnant during sex, which is called the safe period. The probability of conception during the safe period is very low, but women of childbearing age still have extra ovulation, so the safe period is not absolutely safe.

If menstruation is irregular, the ovulation period will not be fixed, and the safe period cannot be accurately calculated. In addition, during ovulation, vaginal discharge will appear transparent and stringy, and the body temperature will also change, and the ovulation period can be roughly judged according to the condition of the vaginal discharge and the change in body temperature. However, when menstruation is irregular, the safe period is not safe, and there is a chance of pregnancy, so it is also necessary to use appropriate contraceptive methods, such as using condoms.

Under normal circumstances, 7 days before and after menstruation is the safe period, but the safe period is not safe, but the chance of pregnancy is low, if you don't want to get pregnant, you still have to do a good job of contraception.

The safe period should be calculated from the date of the start of menstruation, generally 7 days before menstruation and 8 days after menstruation is the safe period, which is not absolutely accurate, and sometimes ovulation will be earlier or later.

According to the menstrual cycle, it is generally the first seven and the last eight. It usually starts on the first day of menstruation, and eight days is the safe period, including seven days before menstruation. Eight days does not refer to the eight days after menstruation is clean, it is generally counted from the day of menstruation, within eight days.

If the menstrual period is only four or five days, after the menstrual period is completely clean, then there is a safe period of about four days. Women generally do not ovulate at this time, but there are usually exceptions.

If the menstrual cycle is regular, it is generally calculated from the first day of the next menstrual period, the 14th day is the day of ovulation, the first 5 days of ovulation and the last 4 days of ovulation, a total of 10 days is the ovulation period A menstrual cycle goes out of the ovulation period and the menstrual period, which belongs to the safe period, but the safe period is not absolutely safe, and it is possible to get pregnant.

In general, the safe period is the first seven days before menstruation and eight days after menstruation. However, there is no absolute safe period, and sometimes due to physical factors or emotional factors, there may even be two ovulations. Therefore, if you are not planning to get pregnant, try to take other reliable measures.

The safe period generally refers to five days before menstruation and six days after menstruation. During this time, the likelihood of pregnancy is lower. It's unlikely, but it's definitely not.

Hello, yes, from the first day of coming, the first seven and the last eight, but not absolutely, many women do not have an absolute safety day, affected by their own life factors, can be advanced, can also be postponed.

Most women have a menstrual cycle of 28-30 days and usually ovulate 14 days before their next menstrual period, with safe periods occurring 4-5 days before and after ovulation date. Eggs can survive for 1-2 days after they are released from the ovaries.

Ovulation is 12 14 days before the next menstruation, 4 5 days before and after ovulation is the fertile period, the rest of the time is the safe period, each person's menstrual cycle is different, the menstrual time is different, only according to the time of ovulation, and ovulation is easily affected by a variety of external factors, may be advanced or delayed, so the failure rate of this method is high.

The safe period is the first seven days and the last eight days of the proverbial period, and the first 7 days and the last 8 days of the menstrual period are safe. The safety period is calculated as: Calculate the date of your next menstrual period, then calculate the date of ovulation, and then determine the safe period.

The safe period is about four or five days after the end of menstruation and about four or five days before menstruation comes, and this period is known as the safe period.

The doctor said that there is no safe period, and no matter how safe you are, there will still be unsafe factors in it, and it is better to use contraception.

This is usually the eighth day after cleaning, or the seventh day before the expected arrival, but it varies from person to person.

In the case of a normal safety period, it is the first seven days of the menstrual holiday, and the last eight days are safe, but it is not certain.

You can divide it by 3 based on your menstrual cycle, with the middle 10 days being the danger period and the 10 days before and after menstruation being the safe period.

After menstruation, within three days, it is relatively safe, and beyond this time, there will be a relatively high probability.

The safe period is not absolutely safe! Unless it's safe a few days before menstruation!

You can also get pregnant during the safe period, so it doesn't make sense to count it or not.

Yes, there is a safe period, seven days before and eight after menstruation, seven days before menstruation and eight days after menstruation, but it is not 100%, it is still the safest with a condom, which can prevent pregnancy and prevent disease!

Yes, the first seven and the last eight of menstruation, understand? But the safe period is not 100% safe, because your period is not accurate every month, so remember to take measures.

7 days before menstruation and 8 days after clean menstruation.

7 days before menstruation and 8 days after menstruation clean, the first seven and the last eight.

The week before and after menstruation is a safe period.

The woman's safe period is divided into two stages: before and after. Counting seven days forward from the day before menstruation is called the pre-safe period. Eight days after menstruation is clean, and counting eight days after menstruation is called the post-safe period.

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. This is the rationale for the rhythm method. 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 5 days before and 4 days after, that is, December 11-20. Except for the menstrual period and ovulation period, the rest.

The period of time is a safe period.
