Do women with regular menstrual cycles have a safe period?

Generally speaking, women with regular menstrual cycles have a relatively safe period. The detailed analysis is as follows:

The safe period is usually divided into the pre-ovulatory safe period and the post-ovulatory safe period. The pre-ovulatory safe period refers to the time from the day menstruation ends to the day before the ovulation period begins, while the post-ovulatory safe period refers to the time from the first day after ovulation ends to the day before the next menstruation begins. During the safe period, the possibility of pregnancy is relatively low because the ovaries have not yet released an egg or ovulation has already finished. However, it should be noted that the safe period is not absolutely safe, as a woman's ovulation can be influenced by multiple factors, such as emotional changes, environmental changes, and health conditions, which may cause changes in the timing of ovulation.

Women are advised to keep detailed records of their menstrual cycles to more accurately estimate the safe and ovulatory periods. This helps women better understand their physiological conditions and improve the accuracy of safe period calculations. At the same time, it is recommended to use reliable contraceptive methods, such as condoms or intrauterine devices, to prevent unintended pregnancies.
