Under normal circumstances, it is possible to get pregnant after the end of a woman’s period, but the probability is relatively small. After the menstrual period, the follicular development of women is still not mature enough, after intercourse, the sperm needs to be combined with the egg cell to be able to get pregnant, and this period of time the probability of maturity of the egg cell is relatively small, so the probability of getting pregnant is also relatively small. In addition, it is not recommended that women have sex just after the end of menstruation, mainly because sex at this stage may make the woman’s uterus more stimulated by bleeding again, but also increase the probability of gynecological diseases. Therefore, it is recommended that women have sex three days after the end of menstruation, and if there is no need to prepare for pregnancy, contraceptive measures should be taken in time to avoid other problems.
