When a girl faces Yin Hong for the first time

　　Finally it was time for school to end. Lan Lan found an excuse to get rid of her friend Lingling's "entanglement" and ran to the open space behind the classroom to sit down alone. She eagerly took out the small mirror in her schoolbag and carefully looked at herself in the mirror, hoping to find some clues about what was different from the past on her delicate and rosy face. Lanlan felt an indescribable feeling in her heart when she thought that she was no longer a little girl. She wants to cry, for the childhood she is about to say goodbye to ； She wanted to cry, because of the adult solemnity and pride that surged in her heart. ； She wanted to know what she should do for Yin Hong's patronage.……

　　Girl friends, are you, like Lan Lan, anxiously looking for answers to the first blush in your life with complicated emotions?

　　In fact, the first appearance of dark red in a girl is called menarche, which is due to the girl's physical development reaching a certain level. Uterus The endometrium periodically undergoes peeling and bleeding under the direct action of sex hormones secreted by the ovaries. The appearance of menstruation will open a new page in your life, which is a sign of maturity. female The 33-35 years you are about to go through have laid the physiological foundation for you to be a wife and mother.

　　Just like an uninvited guest suddenly breaks into your life, you may not be used to the sudden visit of menstruation, and you may even feel a little uneasy about it. An attentive girl may worry about her health when she sees so much blood flowing out of her lower body. healthy . It is true that your physical strength may be relatively weakened during menstruation, but this will not affect your health. Because normal menstruation is not bleeding in the usual sense, we might as well regard menstrual blood as metabolic "waste products" excreted by the body. In addition, our human body has a strong compensatory ability, and the "loss" of physical strength will be replenished soon.

　　After Yin Hong appears for the first time, girls will often find that their menstruation is irregular: sometimes "Yin Hong" occurs frequently, sometimes there is no movement for two or three months, and the amount of menstrual blood is also heavy and sometimes light. However, the menstruation described in the book is regular: the average interval from the first day of this menstruation to the first day of the next menstruation is 28 days, and 20-40 days is also normal. ； The duration of each menstrual period is 3-6 days ； Normal menstrual blood volume is about 60 ml... Could there be something wrong with me? Not really. Generally speaking, during puberty and development, a girl's uterine and ovarian functions are not yet balanced, so it is normal to have irregular menstrual cycles in the years after menarche. Moreover, life changes such as changing schools, relocating, traveling or taking exams, as well as mood swings, will affect the length of the menstrual cycle and the amount of menstrual blood discharge. Even in adulthood, the length of the menstrual cycle varies from person to person, and each woman has her own pattern of menstrual dates. However, if you have had at least one period and then stopped for more than 6 months, you need to Hospital Gynecology Check it out.

　　If you know your partner is menstruating but you haven't noticed anything yet, you may worry that something is wrong with you. In fact, the age of menarche is affected by many tangible and intangible factors, such as race, culture, climate environment, physical fitness, exercise, nutrition and health, etc. Therefore, the age of menarche is different for everyone. In China, overall, urban girls have menarche earlier than rural girls, and contemporary girls have menarche earlier than previous generations. This is mainly due to improved nutrition and the richer cultural stimulation of modern urban society. Even among girls in the same class, there is a big difference in the age of menarche, which is normal. It should be pointed out that if you haven’t had your period yet when you are around 18 years old, you’d better go to the hospital’s gynecology department for some examinations.

　　“What should I do if I suddenly get my period in class, while walking, or during group activities? ”This is a problem that many girls worry about. They are afraid that the bright red will make them "embarrassed" without even realizing it. Generally speaking, the amount of menstrual blood is very small on the first day of menstruation. Even if you wait until after class or school to deal with it, it will not be easy to show the world a "red world". Of course, as the menstrual cycle becomes more regular, you'd better get used to remembering the date of each menstrual period and the number of days between each menstrual cycle. In this way, you can roughly estimate the date of the next menstrual cramp and prepare in advance.
