Different couples will choose different contraceptive methods according to their preferences. In addition to commonly used condoms and birth control pills, contraception can also be achieved by calculating the safe period. Safe contraception can prevent women from getting pregnant and reduce the series of troubles caused by sudden pregnancies between unprepared couples. So, what is the safe period for contraception?
What is the safe period for contraception
1. The seven days before menstruation and the eight days after menstruation are generally safe, with a total of 15 days before and after menstruation, which is the safe period.
2. When is the safe period? The calculation of the safe period is: the day when a woman ovulates, 14 days after the first day of her menstrual cycle, the first 4 days of the 14th day, and the last 5 days are the dangerous period. In addition, there is a safety period.
3. The possibility of pregnancy during the safe period is very small, only about 1-5% (i.e. the probability of not getting pregnant is 95% -99%), and the accidental pregnancy rate of most contraceptive drugs is 10% (i.e. the probability of not getting pregnant is 90%).
Calculation method for safety period
1. Calendar method. If the menstrual cycle is always accurate, ovulation may occur on the 14th day after menstruation. After the egg cells are discharged, they can survive for about 2-5 days, and sperm can survive for 1-3 days when they enter the female reproductive tract. Therefore, not having sexual intercourse 3-4 days before ovulation and 5-7 days after ovulation can avoid pregnancy. A woman with a regular menstrual cycle has a stable ovulation time. Having sexual intercourse during the safe period to achieve contraception is called the safe period contraception method. This method is not suitable for young people because their frequency of sexual intercourse cannot be separated by about a week. This method is suitable for middle-aged people.
2. Basal body temperature method. Basal body temperature refers to the body temperature of a healthy person after waking up in the morning, which is generally the lowest body temperature of the day. Women of normal reproductive age experience an immediate increase in body temperature after ovulation, which persists until the start of the next menstrual cycle. Using the pattern of changes in a woman's basal body temperature, identify her ovulation period and refrain from sexual intercourse for the first 3-4 days and the last 5-7 days.
3. Female vaginal secretions undergo regular changes during different stages of the menstrual cycle. During ovulation, there is an increasing amount of mucus, causing a moist sensation in the vagina. The mucus becomes clear and can stretch up to 10 centimeters in length. The last day this mucus lasts is usually the ovulation period. Not having sexual intercourse for the first 3-4 days and the next 5-7 days.
The calculation of the safe period is accurate, which can avoid the ovulation time of women, the opportunity for sperm and egg to combine, and the phenomenon of pregnancy. However, if the female physiological cycle is unstable, the calculation of the safe period is prone to errors. If contraceptive measures are not taken during this period, pregnancy is likely to occur. Therefore, the method of calculating the safe period for contraception is not suitable for everyone.
