Generally speaking, if you have sex during the ovulation period, the safe period of menstruation is the seven days before and eight days after the menstrual period. The 7 days before and 8 days after the menstrual period are safe, so the probability of pregnancy is relatively large. Then the ovulation period is around the 7th day. At this time, there is no safe period before ovulation to talk about, because you may encounter ovulation right after the menstrual period ends at any time. Therefore, many women need to calculate their ovulation period when preparing for pregnancy. How many days after the menstrual period ends is the ovulation period? The ovulation period is generally about 14 days before a woman's next menarche. The ovulation period is the 5 days before and 4 days after the ovulation period, a total of 10 days within the ovulation period. Therefore, if the menstrual cycle is 30 days, and the ovulation period is 16 days, then the ovulation period is from day 11 to day 20. Generally speaking, the ovaries of women of normal childbearing age only release one egg cell per month. The egg cell can survive for 1 to 2 days after being released, and the sperm can survive for 2 to 3 days in the female reproductive system. The fertilization ability is mostly within 24 hours after ovulation. After 2 to 3 days, the sperm will lose the ability to fuse with the egg cell. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may become pregnant. This stage is called the fertile period or the dangerous period of pregnancy. Women's ovulation period 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, a total of 10 days within the ovulation period, the ovulation period. The other time outside the menstrual period is called the safe menstrual period. The safe menstrual period is divided into the safe menstrual period before ovulation and the safe menstrual period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after ovulation to the day before the next menstrual period is the safe period after ovulation. The safe menstruation period after ovulation is safer than the safe menstruation period before ovulation. Sisters who are preparing for pregnancy should have sex after ovulation as much as possible, as this will increase the possibility of pregnancy. Sisters who need contraceptive measures should avoid having sex after ovulation. However, I think the above calculation method cannot be applied to everyone, after all, there are too many factors that affect women's menstrual cycle. To be on the safe side, you should still use contraceptive methods even if you have sex during the safe period. |
