The girl who didn't have her period means that she hasn't developed yet. If you don't ovulate at this time, you won't get pregnant. Once you start menstruating, it proves that you have begun to develop. At this time, when a girl has sex, it is possible to get pregnant. But for girls, premature sexual relations are not good for their health, and gynecological diseases will also occur.
When menstruation comes, girls are generally 13- 14 years old, and girls with adequate nutrition will menstruate at112 years old. The time of my first menstruation is closely related to genetic factors and nutrition. If/kloc-after 0/5 years old, girls have not menstruated, parents should give their children more nutrition to promote all aspects of development.
It is inevitable that girls will be afraid when they come to menstruation for the first time, so parents must prepare toilet paper and sanitary napkins in their children's schoolbags and teach them how to use them in case of emergency. In addition, during menstruation, some nutrients will flow out of girls' bodies, so parents need to give their children some nourishing foods, such as longan, red dates and chicken soup.
