What are the safe periods for girls?

Many women often mention the ovulation period and the safe period during sexual intercourse. This is because the probability of a woman getting pregnant during the ovulation period is higher, while the probability of getting pregnant during the safe period is lower. Of course, the calculation of the safe period and ovulation period is also related to the time of menstruation, and there is a special set of calculation formulas. So when are the safe periods for girls? Find out more.

1. Except for the ovulation period, other times are safe periods. For women with regular menstruation, ovulation usually occurs about 14 days before the next menstruation, so it can be inferred that the 4-5 days before and after ovulation is the fertile period, and this time is the dangerous period. But in fact, the rhythmic period contraceptive method is not very reliable and should not be promoted. Because the ovulation date is usually determined by the basal body temperature method and cervical mucus observation method. However, the relationship between the curve changes of basal body temperature and the time of ovulation is not constant, and cervical mucus observation requires training to master. So it is best to wear a condom to avoid pregnancy.

2. Normal women of childbearing age have menstruation once every 28 days or so. The period from the beginning of one menstruation to the first day of the next menstruation is called a menstrual cycle. From the perspective of contraception. The period from the day of menstruation to the beginning of ovulation three days before ovulation is the safe period before ovulation. From the first day after the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. The safety indexes of these two safe periods are also different. Generally speaking, the safe period after ovulation is safer.

3. The safe period is divided according to the menstrual period. Generally, we divide the ovulation period into "seven days before and eight days after" which is the seven days before and eight days after the menstrual period. The menstrual period is naturally considered a safe period, but sex should be avoided during the menstrual period because having sex during the menstrual period will increase the risk of female infection and gynecological diseases, and even cause infertility in severe cases. Therefore, we generally exclude the menstrual period from the safe period by default.
