It is normal that the menstrual cycle will be unstable within one to two years after menarche, and it will not be like this when all aspects are fully developed! Don't worry too much. In diet therapy, don't be picky about food, eat more fruits, drink more water and exercise more. If you have menstrual dysmenorrhea, you can drink brown sugar water. You can also eat some supplements, such as red dates and medlar. Keep warm during menstruation, don't wash your hair or take a cold bath. Two years before menarche, you should take good care of it, otherwise you will have dysmenorrhea in the future.

Ps: Abdominal pain, fatigue and backache will occur during menstruation. If you are not familiar with it, you can talk to your mother, and she will tell you more health knowledge. Also, pay attention to hygiene during menstruation, change underwear and sanitary napkins frequently, clean your genitals and keep warm.
