Disease description:

During regular sexual intercourse with my husband, we always take safety precautions. I recently heard from someone that women have a safe period, and I would like to ask the doctor: how many days before menstruation is considered the safe period?

Doctor's answer (1)
Dr. Zhao Xiaodong
A few days before menstruation is considered the safe period, which mainly depends on whether the woman's menstrual cycle is regular. For women with regular menstrual cycles, generally, the seven days before the onset of menstruation can be regarded as a relatively safe period. This is because during this time, ovulation has already ended, and the egg has lost its ability to be fertilized; therefore, the probability of conception during sexual intercourse is relatively low. If a woman has irregular menstrual cycles, calculating the safe period becomes more complicated, and it may even be impossible to determine accurately. However, the safe period is not absolutely safe, as a woman's ovulation may occur earlier or later due to various influencing factors, thereby rendering the safe period ineffective. It is recommended to use other contraceptive methods, such as condoms or oral contraceptives.
