My 12 year old daughter menstruated for the first time ...

Dr. my 12 year old daughter menstruated for the first time in January and came a brown rub for 4 days, in February also the same brown rub for 4 days. Only in March, April and May did not descend but. What's going on with her, please answer me. Thank you!
Expert answer:

This "mess" and "strange menstruation" is normal for some girls in the first months, in case she persists she should take her to a gynecologist.
