Whats a period?
you are very normal to have your period around the same time every month. women dont all get their periods around the beginning of the month! we're all different. it all depends on the day of your cycle, the hormones in you, how much you exercise, etc. Each women is different. Just be very glad you have a predictable period. most of us do not! but you are fine. there is nothing that says that you need to have your period only at the beginning of the month.
you might be an irregualr person. some people have a stable period that comes at a certain time. Your is mixed.
It comes whenever it is ready to.
As long as its every 28 days (give or take a day or two) it is fine.
