Many people speculate women's safe period based on the time of menstruation in order to achieve safe contraception. In fact, the safe period for each woman is different, so the traditional method of measuring the safe period is not suitable for every woman. So, can you get pregnant if you have sex eight days before your period? According to the traditional method of calculating ovulation, having sex at this time will not lead to pregnancy. No, the ovulation period has passed! Ovulation calculation method 1: Estimation method Usually, women ovulate about 2 weeks (12-16 days) before the next menstruation. Therefore, you can calculate it yourself based on the rules of your previous menstrual cycle. However, the ovulation period may change due to the influence of environment, disease, mood and medication, so the calculation of ovulation date should be based on actual conditions. Ovulation calculation method 2: The menstrual date calculation method believes that each ovulation should occur about 14 days before the menstrual period, so the 5 days before ovulation to the 5 days after ovulation are called "ovulation day". However, this method is less reliable because most women have irregular periods. In comparison, the first two methods are more reliable, but somewhat troublesome. Here we introduce you to a simple and more reliable calculation method, hoping it will be helpful to you. The calculation formula is: The first day of ovulation = the number of days in the shortest menstrual cycle minus 18 days The last day of ovulation = the number of days in the longest menstrual cycle minus 11 days Before using this formula to calculate, the individual is required to observe and record his or her menstrual cycle for 8 consecutive times to obtain the longest and shortest days of his or her menstrual cycle. The numbers obtained by substituting into the above formula represent the beginning and end time of the woman's "ovulation period" respectively. (The menstrual cycle is calculated from the first day of the current menstruation to the first day of the next menstruation) For example: the menstrual cycle of a woman of childbearing age in the first 8 months is 30 days at most and 28 days at most. Substituting the formula into the formula is: First day of ovulation = 28 days - 18 days = 10 days Last day of ovulation = 30 days - 11 days = 19 days That is, this woman's "ovulation period" starts on the 10th day of this menstruation and ends on the 19th day of this menstruation. If you observe that your menstruation is very regular: once every 28 days, then you can set the longest and shortest days of your menstrual cycle to 28 days. Substituting them into the formula, you can calculate your "ovulation period" as: day 10-17 of this menstrual period. This calculation method takes the first day of the current menstruation as the base point and counts the days forward, rather than taking the next menstruation as the base point and counting backwards, so it is not easy to make mistakes. After finding out the "ovulation period", if you want to get pregnant, you can start from the first day of the "ovulation period" and have sexual intercourse every other day for several months, and you are very likely to get pregnant. If you don’t want to get pregnant, you have to miss the “ovulation period” to have sex. Although there are some loopholes in the calculation method of the safe period, it does not affect our use. We can calculate the ovulation period and the date to provide a reference for people's contraception. Although having sex eight days before your period does not necessarily lead to pregnancy, it is better to be safe than sorry. It is recommended to all friends that if you do not want children, you can take some contraceptive measures just in case. . |
