Can you get pregnant if you have sex 89 days before your period?

Every woman has a normal menstrual cycle, but the issue that women worry about most is unexpected pregnancy. Therefore, women who do not want children will calculate the time of menstruation. It is not easy to get pregnant in the first seven days and the last eight days, so having sex at this time can avoid pregnancy. Of course, there are many methods of contraception, but the safest and most side-effect-free method is to calculate the menstrual period to prevent pregnancy. So, can you get pregnant if you have sex 89 days before your period?

1. Will having sex a few days before menstruation lead to pregnancy?

Under normal menstruation conditions, the chance of pregnancy during ovulation is higher, and the chance of pregnancy during the safe period is lower. If you are worried about pregnancy, it is recommended that you come to the hospital for a blood HCG test 5-7 days after having sex, which is more accurate.

2. Sex during the safe period

After sperm enters the female reproductive tract, it can maintain its fertilization ability for 1-3 days. After the egg is released from the ovary, it can maintain its fertilization ability for about 30 hours and dies naturally after 48-72 hours.

Taking a 28-day menstrual cycle (from the first day of menstruation to the first day of the next menstruation) as an example, the female safe period we usually refer to as "seven before and eight after" refers to: the seven days before menstruation begins and the eight days after menstruation ends. But this safe period is not absolutely safe, because ovulation may be advanced or delayed by a few days due to many factors. Therefore, you cannot take chances with contraception, and you must choose the best time to conceive.

3. Failure rate of using safe period contraception

The safe period contraceptive method is a physiological contraceptive method. Sexual life is carried out under normal conditions and satisfactory sexual pleasure can be obtained. However, if it is not strictly mastered or used improperly, it can easily lead to failure. According to statistics from relevant foreign experts, the failure rate of safe period contraception is as high as 14.4% to 47%.

The high failure rate of safe period contraception is mainly related to the following two factors:

1. Since the time of female ovulation is affected by factors such as the external environment, climate, one's own emotions, health status and physical condition, ovulation may be delayed or advanced, and extra ovulation may also occur, that is, ovulation twice in a month. This is one of the reasons for the high failure rate.

2. Since hormones in the body can also induce ovulation, when two people have sex, if they are particularly excited, it will increase hormone secretion, which may lead to ovulation. Therefore, this is also one of the important reasons leading to high failure rate.
