Patient's question:
The day each month for women is considered safeDoctor's answer:
Normal fertile women have one menstrual period each month. The time from the start of one menstrual period to the first day of the next is called one menstrual cycle. If considering contraception, a woman's menstrual cycle can be divided into the menstrual period, ovulation period, and safe period. Safe period contraception is a method of birth control that involves abstaining from sexual intercourse during the ovulation period. This is a traditional method of contraception and was one of the commonly used methods before the advent of birth control pills and intrauterine devices (IUDs).A woman's ovulation date is generally about 14 days before her next menstrual period. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days, waiting to be fertilized. Male sperm can maintain fertilizing ability in a woman's reproductive tract for 2-3 days. Therefore, sexual intercourse during the days before and after ovulation increases the likelihood of conception. For safety, the 5 days before ovulation, the 4 days after ovulation, and ovulation day itself are collectively referred to as the ovulation period. Because sexual intercourse during the ovulation period is more likely to result in pregnancy, this period is also called the fertile period or the risky period.
The safe period is divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day after the menstrual period ends to the day before the start of the ovulation period is the pre-ovulation safe period. The period from the day after the ovulation period ends to the day before the next menstrual period is the post-ovulation safe period. The post-ovulation safe period is safer than the pre-ovulation safe period. This is because some women may experience early ovulation due to environmental changes or emotional fluctuations, which shortens the pre-ovulation safe period without their knowledge. This
