The menstrual period in women is actually caused by the atrophy of the corpus luteum of the egg, which stops secreting estrogen and progesterone. At this time, the blood vessels in the endometrium contract, the endometrium dies and falls off, causing bleeding and forming menstruation. So, is menstruation a safe period? Can having sex during menstruation lead to pregnancy? Below is a detailed answer for you.
Not getting pregnant during menstruation is actually a false proposition. Although there is actually a so-called safe period, it is not safe to count it as a safe period because the ovulation date of women actually varies by several days. And having sex during menstruation cannot guarantee 100% not getting pregnant.
In fact, when a woman has her period, another egg is developing and preparing to be released during this cycle. All women have the same menstrual cycle duration, which varies among individuals. Many women have a menstrual cycle of approximately 28 days, while others have a cycle of only 22 days. If your menstrual cycle is short, ovulation may occur a few days after the end of your period. Considering that the survival time of sperm in the fallopian tubes can reach up to 3 days, theoretically, sperm may survive until ovulation, making it possible for you to conceive shortly after your menstrual period.
Pregnancy during menstruation is actually a relatively rare event, but it does not mean that this method can completely avoid pregnancy. Moreover, due to the fact that vaginal bleeding, even uterine bleeding, is required during menstruation, and women's body's resistance will decrease during these days, the risk of infection during intercourse during menstruation is increased.
In summary, having sexual intercourse during menstruation cannot completely avoid the probability of pregnancy. On the contrary, it can increase the risk of infection. Therefore, it is recommended not to use this method of contraception and to choose a more side effect free and safe method. However, it should be noted that no method can achieve 100% contraception.
