Will I get pregnant if I have sex on the first day after my period?

Women are generally not likely to get pregnant if they have sex on the first day after their menstrual period. The menstrual period is 3-7 days, and the safe menstrual period is within 8 days of the first menstruation. Generally, it is not easy to get pregnant. For girls with regular menstrual cycles, the ovulation period is the 14th day before the menarche. The period just after the menstrual period should be considered a safe period, and the chance of pregnancy is very small, but it is not certain, because sperm can survive in the body for 3 days, the egg may be discharged prematurely or there may be an abnormal ovulation period. If you use the safe period of menstruation for contraception for a long time, the probability of failure will be relatively high. The menstrual and ovulation periods will be affected by environmental factors, psychological pressure, dietary factors, diseases, medicines, staying up late, cold stimulation, etc. Therefore, it is not absolutely impossible to get pregnant just after the menstrual period. You should usually take good contraceptive measures.

If you have sex right after your menstrual period and there is no contraceptive method, there is still a possibility of accidental pregnancy. This stage is theoretically called the safe menstrual period before ovulation. The safe period before ovulation is from the first day after the menstrual period is over to 3 days before ovulation. Sometimes women can make ovulation in advance due to changes in their mentality, environmental influences, changes in diet, stress and other factors. At this time, the safe period before ovulation will be shortened, and they are not aware of it. In this way, the safe period before ovulation is not very safe. There is still a possibility of unwanted pregnancy if there is no contraceptive method for sexual life.

The safe menstrual period is related to each woman's longest menstrual cycle, the shortest menstrual cycle, and the beginning of the menstrual period. The safe menstrual period is not absolutely safe. Sometimes women ovulate early or late, and it becomes invalid to judge the safe period of menstruation at this time. Identifying the safe menstrual period only reduces the chance of pregnancy and is not a measure of contraception.

It is generally not easy to get pregnant right after the menstrual period. Generally, the possibility of a safe menstrual period is relatively high at this time. Of course, in this case, you need to check whether the menstrual cycle is normal. If the menstrual cycle is normal, the time just after the menstrual period belongs to the safe menstrual period. However, if the menstrual cycle is abnormal, the ovulation period cannot be completely determined at this time. Even if the menstrual period has just ended, there is a possibility of ovulation. Therefore, contraceptive methods must be taken at this time.
