Is it safe to have sex three times before and four times after menstruation?

I believe that the first three days and last four days of menstruation are issues that many couples who have been living together are concerned about. Why is this? Many people believe that the first three days and last four days of menstruation are women's safe period. If you have sexual intercourse during this time, there will be no accidental pregnancy even if you forget to take contraceptive measures. Although many people believe this statement, there are still many people who have doubts. Is it really safe to do it three days before and four days after menstruation?

The safe period is divided into the safe period before ovulation and the safe period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. Generally speaking, the safe period after ovulation is safer than the safe period before ovulation. This is because some women sometimes affected by environmental changes and mood swings affect the advance of the ovulation, so before the safe period ovulation will be shortened, but did not know their own, so before the safety period ovulation is not safe. The opportunity that the ovary has row two eggs in a menstrual cycle is very rare, that is, after ovulation to the next menstrual cramps before this period of time usually won't happen again the second time of ovulation, so the safety period after ovulation is relatively safe.

Some people simply summarize the safe period for women as the first three days and the last four days, while others say the first seven and the last eight days (often mentioned in Hong Kong and Taiwan films). However, these are not accurate. In fact, it should vary from person to person. Usually a woman's ovulation day is 14 days before menstruation. Taking into account factors such as the survival time of sperm in the female body and errors, the period between 5 days before and 4 days after ovulation is generally called the "dangerous period". The possibility of pregnancy during this period is relatively high. The other time becomes the "safe period" and it is relatively difficult to get pregnant. In addition, it is obvious that the "safe period" after the "dangerous period" has a higher safety factor.

The safe period algorithm also has certain limitations. For example, some women have irregular menstruation and are not suitable for using the safe period for contraception. In addition, women may also have irregular ovulation due to emotional changes.

Through the experts’ explanation, I believe everyone has their own opinions on the issue of the first three and last four days of menstruation. Although the first three days and last four days of menstruation are women's safe period, due to different personal physical conditions, the so-called safe period is not necessarily safe. It still exists risks. Therefore, you should not blindly believe in such statements, but take contraceptive measures as usual to prevent accidental pregnancy from happening in your life.
