For couples who are not prepared for pregnancy, contraception is a very important issue. At present, there are many contraceptive measures that we can take. Taking contraceptive pills and using condoms, we also suggest that everyone should master some basic contraceptive knowledge. Today, let's take a look at when roommates are not pregnant.
In China, in order to solve the problem of "when to share a room and not get pregnant", it is often necessary for female friends to accurately grasp the danger period and safety period.
In fact, it is also possible to get pregnant during the safe period. For women with regular menstrual periods, you need to calculate when the next menstrual period will come. From the first day of the next menstrual period to minus 14 days, this day is the ovulation period. 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. The first 4 days and 5 days of the ovulation period are dangerous periods and are prone to pregnancy.
Dates other than the critical period are considered safe periods, but with low risk, there is still a possibility of pregnancy. Therefore, it is important to pay attention to contraception.
The first step in using safe period contraception is to accurately measure the ovulation period. The three methods currently used to determine ovulation period each have their own advantages and disadvantages: the calendar method can be used to calculate the ovulation period and the safe period before and after ovulation. But it is only applicable to women with normal menstruation, and sometimes ovulation is delayed or advanced due to environmental and emotional changes, so it is not accurate enough.
The basal body temperature measurement method can determine the ovulation date and the post ovulation safety period, but cannot determine the pre ovulation safety period in advance. This method is troublesome and strict. If the body temperature is not measured according to the regulations, the ovulation date cannot be accurately measured.
The cervical mucus observation method can determine the ovulation period, pre ovulation, and post ovulation safety period with high accuracy, but users must be trained and fully mastered before using it.
So, it is best to combine the three methods mentioned above when solving the problem of when to have sexual intercourse without pregnancy. This type of insurance coefficient is larger and the effect will be more ideal.
