Patient's question:
What are the specific days of the physiological safe period. Is it really impossible to get pregnant during these days?Doctor's answer:
Hello:A woman has her menstrual period once a month. The time from the start of this period to the first day of the next period is called one menstrual cycle. Each menstrual cycle is divided into the menstrual phase, ovulation phase, and safe period. A woman's ovulation date is usually about 14 days before her next period.
An egg can survive for 1-2 days in the fallopian tube, waiting to be fertilized. 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 pregnancy. For safety, we consider the 5 days before ovulation, the day of ovulation, and the 4 days after ovulation as a total of 10 days, known as the ovulation phase. Because sexual intercourse during the ovulation phase 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 days from the day the period ends to the day before the start of ovulation are considered the pre-ovulation safe period. The days from the day after ovulation ends to the day before the next 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, making it less safe. It is rare for a woman to ovulate twice in one menstrual cycle, meaning that there is usually no second ovulation between the end of ovulation and the start of the next period. Therefore, the post-ovulation safe period is considered safer.
The chances of pregnancy are very low.
