What are the absolute safe periods for women?

From the perspective of contraception, we divide a menstrual cycle into three periods: the absolutely safe period, the safe period and the dangerous period.

What are the absolute safe periods?

If you have sex during the absolutely safe period, it is almost impossible to get pregnant, unless there are extremely special circumstances where there are 2 or more ovulations in one cycle; if you have sex during the relatively safe period, the chance of contraceptive failure is greater. Many people think that safe period contraception will not affect sexual pleasure and is very convenient, so many young women are keen to use this contraception, and many women who have just given birth also rely on calculating the safe period to prevent pregnancy.

From a theoretical point of view, based on the female ovulation period and the survival time of sperm and eggs in the female reproductive tract, calculating the period of infertility and having sex can indeed achieve the purpose of contraception. Generally speaking, except for the ovulation period, the rest of the menstrual cycle is called the safe period. However, women's ovulation will be affected by many factors such as the external environment, climate, personal emotions, and health status, and may be advanced or delayed by a few days. Therefore, the safe period is divided into absolute period and relative period.

Assuming a menstrual cycle (from the first day of menstruation to the first day of the next menstruation) is 28 days, ovulation occurs around the 14th day. The 3-5 days before and after ovulation are the fertile period, which is a dangerous period for contraception. Days 1-7 and the last 4-5 days of the cycle are when ovulation has not occurred or the egg has died, which is an absolutely safe period. The remaining days are relatively safe periods, because ovulation may be advanced or postponed a few days due to many factors, so it is called relatively safe.

What should you pay attention to during safe period contraception

Safe period contraception is only suitable for couples with regular menstrual cycles, long-term cohabitation, regular lifestyles, and mutual cooperation and understanding. However, due to its low safety, women who use this method of contraception should pay attention to the following points:

1. Many diseases can change women's ovulation time, such as endocrine diseases, kidney diseases, etc. If you use the "safe period" contraception during this period, it can often lead to contraceptive failure.

2. Having sex during menstruation generally does not lead to pregnancy, but there is a possibility of accidental ovulation during menstruation, and having sex during menstruation can easily cause infection, which has more harm than good.

3. If a woman is in menopause and there is still a small amount of vaginal bleeding, she should not have sex until the fourth day after the bleeding stops, because this bleeding may be caused by ovulation.

4. If you switch from oral contraceptives to safe period contraception, you may experience extra ovulation or irregular menstruation in the first few months after stopping the contraceptives, so you should avoid safe period contraception as much as possible during these months.

Finally, we would like to remind all our female friends that contraception during the “safe period” is not always safe and is not worth promoting. Please choose a better contraceptive method based on your specific situation. After all, a failure in contraception will cause serious physical and mental trauma to oneself.
