Are the 10 days before menstruation a safe period?

The 10 days before menstruation is the ovulation period. For women with normal regular menstruation, the menstrual cycle is 28 days. The 7 days before menstruation is the safe period. The chance of conception during the safe period is relatively low. The ovulation period is about 10 days, and the 14 days before the next menstruation is the ovulation period. Women can calculate the regularity of their menstrual period according to their own menstrual cycle.

Is the 10 days before menstruation a safe period?

For women with regular menstruation and a menstrual cycle of about 28 days, the 7 days before menstruation are the safe period. Ovulation occurs about 14 days before the next menstrual period. The ovulation period, which includes the ovulation day, the 5 days before and the 4 days after, is about 10 days in total. Except for the menstrual period and ovulation period, the rest of the time is the safe period. The ovulation period is also the dangerous period, so in order to calculate the safe period, you must first determine your ovulation period. Commonly used methods for calculating ovulation period include menstrual cycle estimation method, ovulation test paper test method, basal body temperature measurement method and vaginal secretion observation method. With the help of the above methods, you can calculate the ovulation period and thus know your safe period.

a. If your menstrual cycle has been 28 days for a long time, you can handle it according to the first seven and the last eight days, because in this way, you can avoid the dangerous period of 10 days.

b. For a woman who often has short cycles, such as a 21-day cycle, the ovulation day is around the 7th day. At this time, there is no safe period before ovulation, because the minimum reserved period before ovulation may occur at any time just after the menstrual period ends. For such women, there may be a risk of pregnancy even if their menstruation has just ended.

c. For a woman who often has a long cycle, such as a 35-day cycle, the ovulation day is around the 21st day. The delayed ovulation at this time makes it impossible to determine the safe period after ovulation.

Are the two days before menstruation a safe period?

The method of calculating ovulation based on the menstrual cycle is also called the calendar method. Both menstruation and ovulation are affected by the endocrine hormones of the pituitary gland and ovaries, and finally show periodic changes. The length of the cycles of the two dates is actually the same, that is, there is one cycle each month, and ovulation occurs in the middle of two menstruations. Women’s menstrual cycles can be long or short, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days.

Based on the special relationship between female ovulation and menstruation, we can calculate our ovulation period according to this menstrual cycle. The calculation method is to start from the first day of the next menstruation, and count down to fourteen days or subtract fourteen days, which is the so-called ovulation day. The ovulation day, the previous 5 days and the next 4 days together are called the ovulation period. This is the theoretical basis of the safe period contraceptive method. For example, a girl's menstrual cycle is about 28 days. The first day of this menstruation is December 2nd. Then her next menstruation will be on December 30th (December 2nd plus 28 days). Then subtract 14 days from December 30th, and December 16th is the ovulation day.
