When is the safe period?

In daily life, people often talk about the safe period, but some people still don't know much about it. However, married women basically know the safe period. If you have sex during a woman's safe period, the chance of pregnancy is usually very low. Although everyone knows the safe period, many people don't know how to calculate the safe period by themselves. When is the safe period for women?

When is the safe period for women?

Except for the menstrual period and ovulation period, the rest of the time is a safe period. Women's safe period is divided into safe period before ovulation and safe period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation.

A woman's ovulation period is generally about 14 days before the next menstrual period. To be on the safe side, we call the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days, the ovulation period. Generally speaking, the ovaries of women of normal childbearing age release only one egg per month. The egg can survive for 1-2 days after being released, and the sperm can survive in the female reproductive tract for 2-3 days. The fertilization ability is mostly within 24 hours after ovulation. After 2-3 days, the sperm loses the ability to combine with the egg. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may get pregnant. This period is called the fertile period or the dangerous period.

How to calculate the safe period for women?

The safe menstrual period refers to the period from the end of the last ovulation period to the next ovulation period. Generally speaking, if a woman has a 28-day normal menstrual cycle, the seven days before and eight days after the first day of menstruation is the safe period, which is often referred to as "seven before and eight after". The seven days before menstruation and eight days after menstruation are the safe period for adult women, which is a calculation method used by most people for contraception. In addition to the calendar method that uses days to calculate, the female safe period can also be calculated using the basal body temperature method and secretion observation method. However, the safe period for contraception is not absolutely safe. Sometimes women ovulate earlier or later, and the judgment of the safe period becomes invalid at this time.

What are the safe periods?

The safe period refers to the period from the end of the last ovulation period to the next ovulation period. Generally speaking, if a woman has a normal menstrual cycle of 28 days, the seven days before and eight days after the first day of menstruation is the safe period. The seven days before menstruation and eight days after menstruation are the safe period for adult women, which is a calculation method used by most people for contraception. In addition to the calendar method that uses days to calculate, there are also the basal body temperature method and the secretion observation method. However, the safe period is not absolutely safe. Sometimes women ovulate earlier or later, and the judgment of the safe period becomes invalid at this time.

Is the first seven and the last eight a safe period?

The "first seven" and "last eight" are a method used to calculate the safe period. The "first seven" refers to the seven days before menstruation, and the "last eight" refers to the eight days starting from the first day of menstruation. It should be noted that "the last eight" does not refer to the eight days after the end of menstruation. If a woman starts menstruating on September 20 and ends on September 26, then the "first seven" refers to the seven days starting on September 13, and the "last eight" refers to the eight days before September 27. That is, the period from September 13 to September 27 is the woman's safe period.

However, the "seven before and eight after" of a woman's safe period should be determined according to the menstrual cycle. This method of calculating the safe period is generally suitable for women with a menstrual cycle of about 28 days and regular menstruation. If a woman's menstrual cycle is less than 26 days, generally speaking, the "first seven" can still be calculated as a safe period, but the "last eight" does not apply. Contraception during the safe period can also be affected by factors such as mood, climate, and environment, which may result in early ovulation, delayed ovulation, or even extra ovulation. Therefore, contraception during the safe period is not absolutely safe.
