Is a woman's safe period or ovulation period a few days before menstruation?

　　The safe period is a method of calculating contraception. Compared with contraceptive methods such as birth control pills, calculating the safe period has lower side effects, so it is chosen by most people. The safe period contraceptive method requires accurate timing to reduce the chance of contraceptive failure. In this regard, someone asked how many days before menstruation is safe period Or is it ovulation? How to calculate the safe period for women? Next, I will introduce them one by one for your reference.

　　Is it a safe period or ovulation period a few days before menstruation?

　　Is it a safe period or ovulation period a few days before menstruation? Traditionally, the seven days before menstruation are a safe period for adult women.

　　The safety period is divided into a safety period before ovulation and a safety period after ovulation. The period from the day of menstruation to the day before ovulation begins is the period before ovulation. From the first day after ovulation to the day before the next menstrual cramps is the safety period after ovulation.

　　In addition to the calendar method using days, there are also safe period calculation methods such as the basal body temperature method and the secretion observation method. It is worth noting that the safe period is not absolutely safe. Sometimes women will ovulate early or delayed, and the judgment of the safe period will become invalid. Determining the safe period can only reduce the chance of pregnancy.

　　How to calculate the safe period for women?

　　Regarding how to calculate the safety period, many people must be concerned about this issue. Next, I will introduce a few How to calculate women’s safe period , for your reference.

　　1. Calendar monitoring method

　　This method is based on the menstrual cycle, so the first thing you need to figure out is what your menstrual cycle is.

　　First of all, you need to find a calendar and record in detail when your period comes and when it ends every month. This record should be at least six months old. A cycle is from the first day of menstruation to the first day of menstruation next month. Next, pick the shortest period and the longest period among these periods. Subtract 11 from the longest period of days, and the first day of the safe period comes out. The shortest cycle minus 18, the first day of the fertile period is also out.

　　Finally, let me give you an example. For example, if the shortest menstrual cycle is 28 days and the longest is 31 days, then the safe period starts from the 20th day after menstruation this month (31-11=20 days), and the fertile period starts from the 10th day after menstruation this month (28-18=10 days).

　　2. Basal body temperature measurement method

　　Basal body temperature is also called resting body temperature. After a woman ovulates, progesterone secretion increases, which can increase basal body temperature (by more than 0.3 degrees Celsius), indicating that ovulation has been completed. The day when the body temperature in the body temperature record chart goes from low to high is the day of ovulation. The 5 days before the ovulation day and the 3 consecutive days thereafter are the fertile period and it is not suitable to have sex.

　　3. Cervical mucus observation method

　　The time of ovulation can be observed based on the physical and chemical properties of cervical mucus. After the menstrual period, because the level of estrogen is still relatively low, the secretion of cervical mucus is very little, and women have no liquid feeling at the vaginal opening, which is also called the "dry period." As the level of estrogen increases, the amount of cervical mucus increases. Women can use two fingers to take the mucus from the vaginal opening. The cervical mucus is thin and transparent near the ovulation period, which is called the "peak day". The period with mucus is the period of easy pregnancy, and it is not suitable to have sex. You can only have sex 3 days after the dry period and mucus peak period. If you want to prevent pregnancy during the safe period, you might as well try this Calculate safe period method。
