Will ovulation occur during menstruation? Can you get pregnant during menstruation?

A woman's ovulation period is generally about seven days after her period. At this time, if a man and a woman have sex, there is a possibility of pregnancy. The menstrual period of women is a stage when the body's resistance decreases. It is recommended not to have sex during this period, otherwise women are at risk of contracting gynecological diseases. Therefore, women’s menstrual period and ovulation period are two different physiological stages, and ovulation does not occur during menstruation.

1. First of all, we need to understand what women's menstrual period is. Women have their period every month because they ovulate an egg every month. The sperm and egg combine to develop into an embryo, and after ten months of gestation, a baby is born.

2. If the sperm and egg cannot combine together, the egg cannot survive in the uterus for a long time (about three days) and will be discharged from the body with the shedding of the endometrium. This is what people often call menstruation.

A woman's ovulation period is generally between two menstrual cycles. We can roughly infer that, from the first day of menstruation this month, push back 14-15 days, which is basically her ovulation period. If you have sexual intercourse within ten days before or after ovulation, you may get pregnant. If you have sex on other days, the possibility of pregnancy is extremely small, which is what people often call the safe period.

3. Most women ovulate around the 14th day after the start of menstruation, but if the ovulation period is early and the sperm is vigorous, pregnancy is very likely to occur. The average number of sperms a man ejaculates at one time is about 300 million. These sperms can survive in a woman's body for about 7 days. If the woman ovulates early, pregnancy is very likely.

4. Both menstruation and ovulation are affected by endocrine hormones from the pituitary gland and ovaries, and show cyclical changes. The length of their cycles is the same, both occurring once a month, and ovulation occurs between two menstrual periods. Therefore, ovulation does not occur during menstruation. Ovulation date 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.

However, emergency contraceptive pills can disrupt menstruation and cause irregular ovulation. In addition, emotional excitement or other stimuli may also lead to extra ovulation. Therefore, safe period contraception is not very accurate.

Can I have sex during menstruation? Can I have sex during menstruation?

The menstrual period is the process of shedding female endometrial tissue. At this time, the cervix is ​​open. If you have sexual intercourse during this period, bacteria may be brought into the pelvic cavity and cause infection. At the same time, the menstrual period is also a time when women's immunity decreases. At this time, you should pay attention to hygiene, avoid overwork, and avoid catching cold.

1. The first reason why women cannot have sex during menstruation is to prevent reproductive system infection.

When a woman has her menstrual period, the endometrium (the layer of tissue inside the uterus) peels off piece by piece. When women have sexual intercourse during menstruation, it is easy for bacteria around the vulva and perineum (the area between the vaginal opening and the anus) to be brought into the vagina, cervix and even into the uterus. The bacteria grow and multiply where there is blood, causing inflammation on the spot, which is called endometritis. Not only does it cause fever and lower abdominal pain, but it also causes increased menstrual bleeding and prolonged menstruation.

If the infecting bacteria are highly virulent, they may spread to the outside of the uterus through the lymphatic vessels of the endometrium, enter the pelvic cavity, and cause acute adnexitis (including the fallopian tubes and ovaries) and pelvic peritonitis. This will not only cause fever and abdominal pain, but may also affect future fertility. Once the fallopian tubes become inflamed, adhesions may occur. In severe cases, the lumen of the tubes may be blocked, and conception may be impossible as sperm cannot pass through.

2. The second reason why women cannot have sex during menstruation is to prevent the endometrium from flowing back into the pelvic cavity and causing endometriosis (normally, the endometrium flows out with menstrual blood during menstruation)

If you have sex during your menstrual period, when the woman's excitement reaches its peak, the uterus will contract. At this time, the endometrial fragments that have fallen off the uterine cavity can enter the fallopian tubes with the pressure of the uterine contraction, and then enter the abdominal cavity and pelvic cavity along the fallopian tubes. No matter where they fall, they will grow on the spot, causing endometriosis.
