I just my got my period, any advice?

Okay hear I go..... You just got your period so do not worry if it comes any sooner or any later than 28 days. Your period will be irregular for many years, I am 18 and my period has only just because regular! You don't need to keep a pair of jeans but if you really feel like you might leak then you can. But if you start your period in school it most likely will only go into your underwear, you will probably know if you are going to get it at school and you might start it when you go to the bathroom. The only places to keep pads are pockets or backpacks, maybe you could ask the nurse to keep them for you and if you need to change it you can ask to go see the nurse and do it there! Good luck!! :)
