Patient's question:
Doctor: Hello! When is it generally safe to have sex without getting pregnant?Doctor's answer:
The date of ovulation for women is generally about 14 days before the next menstrual period. For safety, we consider the 5 days before ovulation, the 4 days after ovulation, and ovulation day itself as a total of 10 days, known as the fertile window. The rest of the time, except for the menstrual period, is called the safe period.The safe period is divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day the menstruation ends to the day before the start of the fertile window is the pre-ovulation safe period. The period from the day after the fertile window 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 ovulation earlier due to environmental changes or emotional fluctuations, which shortens the pre-ovulation safe period without their knowledge, making it less reliable. The chance of an ovary releasing eggs twice in one menstrual cycle is extremely rare. In other words, once ovulation occurs, there is usually no second ovulation until the next menstrual period.
Suggestion: Therefore, the post-ovulation safe period is relatively safer.
