Many female friends use the safe period for contraception, but sometimes contraception fails during the safe period. What are the absolute safe periods? What problems should I pay attention to during the rhythm of contraception? Check out Dora's introduction below!
When is the absolute safe period?
From the perspective of contraception, we divide a menstrual cycle into three periods: the absolute safe period, the safe period and the dangerous period.
What is the absolute safe period
If you have intercourse during the absolute safe period, it is almost impossible to get pregnant, unless there is a very special situation, that is, there are 2 or more ovulations in a cycle; and during the relatively safe period, the chance of contraceptive failure is higher. many people think that rhythm contraception will not affect the pleasure of sex, and it is very convenient, so many young women are keen to use this contraceptive, and many women who have just given birth also rely on the estimated rhythm for contraception.
From a theoretical point of view, according to the ovulation period of women and the survival time of sperm and eggs in the female reproductive tract, it is calculated that intercourse during a period of infertility can indeed achieve the purpose of contraception. In addition to the ovulation period, the rest of the menstrual cycle is called the safe period. However, female ovulation will be affected by various factors such as external environment, climate, personal mood, and health status, which may be advanced or delayed a few days, so the safe period is divided into absolute period and relative period.
Assuming that a menstrual cycle (from the first day of menstruation to the first day of the next menstrual period) is 28 days, ovulation is about the 14th day, and the 3-5 days before and after ovulation is the fertile period, and it is the dangerous period for contraception; Days 1-7 and the last 4-5 days of the cycle are absolutely safe periods when ovulation has not occurred or the eggs have died; the rest of the days are relatively safe periods, because ovulation may be affected by many factors in advance or delayed a few days, so called relatively safe.
What problems should be paid attention to during the safe period of contraception
Rhythm contraception is only suitable for couples with regular menstrual cycles, long-term cohabitation, regular life, and mutual cooperation and understanding between the two parties. However, based on its low safety, women who use this method of contraception should pay attention to the following points:
1. Many diseases can change the time of ovulation in women, such as endocrine diseases, kidney diseases, etc. If you use "safe period" contraception during this period, it can often lead to contraceptive failure.
2. Menstrual intercourse generally does not lead to pregnancy, but there is the possibility of accidental ovulation during menstruation, and menstrual intercourse can easily lead to infection, which is harmful but not beneficial.
3. If it is a woman of menopausal age, when there is still a small amount of vaginal bleeding, you should have intercourse on the fourth day after the bleeding stops, because this bleeding may be caused by an ovulation.
4. If you switch from oral contraceptives to rhythm contraceptives, additional ovulation or irregular menstruation may occur in the first few months after stopping contraceptives, so rhythms should be avoided as much as possible in these months. contraception.
Finally, we would like to remind all female friends that "rhythm" contraception is not all safe and is not worth advocating. Please choose the best contraceptive method according to your specific situation. After all, a contraceptive failure will bring serious physical and psychological trauma to oneself.
