Few days after the menstrual period is the safe period.

Generally speaking, a few days after the menstrual period are considered the safe period, which depends on whether the woman's menstrual cycle is regular. For women with regular menstrual cycles, the safe period is roughly 8 days after the end of menstruation and 7 days before the next menstrual period. However, it should be noted that the safe period is not absolutely safe, because a woman's ovulation may be influenced by various factors and thus change, meaning there is still a possibility of pregnancy. Specifically, if a woman has a 28-day menstrual cycle and her period lasts for 5 days, her safe period would roughly be 3 days after her period ends and 7 days before the next menstrual period. However, this is only a rough estimate since each woman's physiological cycle may vary. Furthermore, the safe period method is not a reliable contraceptive method because ovulation may occur earlier or be delayed due to various factors such as emotions and lifestyle habits. Therefore, if there is no plan for pregnancy, it is advisable to adopt more reliable contraceptive measures, such as using condoms or taking contraceptive pills. If necessary, please consult a professional doctor or related institution.
