Is the chance of pregnancy during the safe period high? How to calculate the safe period

In order to have a better life together, many newly married couples will take some contraceptive methods, and the safe period is the most widely used contraceptive method. So is the chance of pregnancy during the safe period high? How to calculate the safe period? The following editor will explain them one by one, hoping to help you.

Is it possible to get pregnant during the safe period?

Normally, you cannot get pregnant during the safe period. This is because women in the safe period will not discharge mature eggs. Even if viable sperm enters the reproductive tract, no fertilized eggs will be formed, and pregnancy will not occur. Of course, if your judgment of the safe period is biased, and you mistakenly count the ovulation period as the safe period, then it is possible to get pregnant during the safe period. Another situation is that the ovulation period and the safe period are only a rough estimate. The time of female ovulation is affected by external factors such as the external environment, emotions, and diet. It may be delayed or advanced, and additional ovulation may occur. In this case, pregnancy during the safe period may also occur. Therefore, if there is no requirement for fertility, it is recommended to use contraception in a timely manner.

How to calculate the safe period

Theoretically, the ovulation time for women with regular menstrual cycles is 14 days before the next menstrual period. If the menstrual cycle is earlier, such as 23 days and the menstrual period is 7 days, then 23-14-7 is exactly the second clean day, which is the ovulation time, which means there is a chance of pregnancy. If the menstrual cycle is more than 25 days, the probability of pregnancy is extremely low. If the cycle is more than 25 days, the safe period is from the tenth day of menstruation, and after ovulation, that is, the first 10 days of menstruation next month, it is relatively safe. For women with irregular menstrual cycles, the ovulation period and safe period cannot be accurately estimated, so the general safe period and ovulation period are for women with regular menstruation.

Is the safe period contraceptive method really safe?

Ovulation prediction is difficult, with an efficiency of only 65% ​​to 95% (95% efficiency can only be achieved with accurate prediction, and accurate prediction of ovulation requires special training). The wide range of variation in efficiency is because women may ovulate at any time of the month, and the ovulation period is different in different months. Due to changes in personal constitution, climate, diet, mood, environment, hormones in the body, etc., the ovulation period often fluctuates, and even extra ovulation occurs, resulting in a high contraceptive failure rate.
