I got pregnant 1 day before my period.

Generally, it is divided into safe menstruation period and safe period according to whether the woman is in the ovulation period. The safe menstruation period means that the woman does not ovulate during this period, and the possibility of pregnancy through intercourse is not big, while the safe period means that the woman is in the ovulation period, and the possibility of pregnancy through intercourse is very high. So, can you get pregnant if you have sex the day before your period? Below, let’s take a look together.

The safe menstruation period generally refers to the 7 days before menarche and 8 days after the end of menstruation, but it is only relatively safe. If you use the safe period for contraception, it is not reliable. Generally speaking, the 3 days after the end of menstruation and the 3 days before menstruation are safer in the safe menstruation period, and it is generally not easy to get pregnant. However, the safe period of menstruation is only relative. Women's ovulation period may be early or late depending on the temperature, environment, physical condition, and other factors. Therefore, it is possible to get pregnant even if the safe period of menstruation is not safe.

The cycle is regular, and the ovulation period is generally relatively stable. Therefore, if you have sex the day before your period, it should be during the safe menstrual period, which means that the possibility of pregnancy is normally very low. However, it is also possible that you had intercourse without contraception at other times in this cycle. If so, it is possible that pregnancy occurred at that time. In addition, if a woman's menstrual cycle is unstable, the time of ovulation will not be fixed, and pregnancy is possible at any time, so it is possible to get pregnant if you have sex the day before your period.

Therefore, if a female friend with a normal menstrual period is in the safe menstruation period the day before her menstrual period, the possibility of pregnancy is relatively low if she has sex. However, this safe menstrual period is not certain and pregnancy is still possible. But for women with irregular menstrual periods, there is no fixed ovulation time, so pregnancy is possible at any time.
