Can you get pregnant if you have sex right after your period?

Generally speaking, "having sex" refers to sexual intercourse, and "menstrual period" refers to the period of menstruation. Whether pregnancy can occur shortly after the menstrual period mainly depends on factors such as a woman's menstrual cycle and ovulation timing. If a woman has a regular menstrual cycle and normal ovulation, pregnancy may not occur. If the menstrual cycle is irregular and ovulation is also abnormal, pregnancy may not occur either. Detailed explanations are as follows:

If the menstrual cycle is consistently regular and ovulation doesn't occur earlier or later than expected, having sex immediately after menstruation usually won't result in pregnancy. This time is considered the woman's safe period, during which ovulation generally doesn't happen, so the chance of pregnancy may be low.

However, if the menstrual cycle is consistently irregular, with either earlier or delayed periods, the ovulation period may also shift accordingly. Therefore, the time immediately after the menstrual period ends may not necessarily be the safe period, and there still may be a possibility of ovulation. Thus, having sex soon after the menstrual period could potentially result in pregnancy.

If pregnancy is not currently desired, appropriate contraceptive measures should be taken, such as using condoms or taking oral contraceptives, to prevent unintended pregnancy. At the same time, ovulation should be monitored regularly to help plan the timing of conception based on ovulation patterns.
