How do I get my period to come faster?

If I masterbate will my period come faster or slower. I haven't masterbated for like a month and a half. I just really want to. Im only 13 and a virgin but I always want to finger my self. I have a huge urge to masterbate. But I really want my period to come faster and I don't want it to slow down because I finger my self. I start school soon and I don't want to deal with my period on the first day. Does any one mm now how I can get my period to come faster. I have the urge to finger my self and when I continue to do it for like 1-4 hours it depends, because my brother will bang on the door and will annoy me and ask if he can come to my room to watch TV.
