How many days are there during the dangerous period of pregnancy

For many women, they do not know how to calculate their dangerous period of pregnancy, which often leads to unexpected pregnancy and causes a lot of trouble. Therefore, we women need to understand the calculation method and number of days for the dangerous period of pregnancy. Below I will give you some details about how many days the dangerous period lasts. I hope you will read it.

Many women want to know how to calculate the dangerous period of pregnancy. Experts say that the dangerous period of pregnancy means effective contraception and successful conception, so the dangerous period of pregnancy can be calculated. However, due to different circumstances of women themselves, the calculation method of the dangerous period of pregnancy may be different. Here is how to calculate the dangerous period of pregnancy. 1. Ovulation time First of all, for women with regular menstruation, the dangerous period of pregnancy can be calculated based on the menstrual cycle. Generally, the ovulation period is about 14 RR before the next menstruation. If the woman's menstrual cycle is 28 days, her ovulation period should be around the 14th day of the menstrual cycle; if the woman's menstrual cycle is 40 days, her ovulation period should be around the 26th day of the menstrual cycle (that is, about 14 days before the next menstruation). The 4 days before and 5 days after ovulation are unsafe periods, and the rest of the time is a safe period, but pregnancy is also possible during the safe period. According to the survival time of sperm and egg, conception is generally easy to achieve within about one week before and after ovulation, so this is considered to be the dangerous period of pregnancy. 2. Determine the basal body temperature. By calculating the dangerous period of pregnancy using this method, women can accurately grasp their ovulation period. Basal body temperature measurement refers to the oral body temperature measured after 6 to 8 hours of sleep, when you wake up without doing any activities (such as talking, eating or getting up, etc.). The temperature records measured by date are connected into a curve, which is called the basal body temperature curve. Because the progesterone secreted by the ovaries after ovulation can stimulate the body temperature center to increase body temperature, the basal body temperature of those who ovulate is low in the first half of the menstrual cycle, while the basal body temperature in the second half, that is, after ovulation, rises. Generally, the temperature difference between the two can reach about 0.5°C, thus showing a biphasic change with ups and downs on the basal body temperature curve. If there is no ovulation, the basal body temperature curve will be flat and unchanged and will be monophasic. The ovulation period is usually when the body temperature drops and then rises again on the curve, which is also the dangerous period of pregnancy. In some women, or during some menstrual cycles, the body temperature may not drop significantly or may not drop at all, but as long as the body temperature starts to rise, it can be considered that ovulation has occurred. During the dangerous period of pregnancy, women whose body temperature changes during ovulation are not obvious can measure several more menstrual cycles so that they can understand their own ovulation patterns. In addition, factors such as cold, fever, or use of progesterone should be ruled out when measuring basal body temperature. The above introduction is the method of calculating the dangerous period of pregnancy. Women can choose the appropriate method to calculate the dangerous period of pregnancy according to their specific circumstances.

The above introduces the number of days in the dangerous period. If we know how to calculate the number of days in the dangerous period of pregnancy, it can help us take good contraceptive measures. I hope it can help everyone in life. I wish you all a happy life!
