Period Problems!?

I think this is my 8th time getting my period. My 7th time was on April 12. And i'm cramping a lot so i think i'll get it soon. but even if i do get it tommarow it'll be a 20 day cycle instead of a 28!! I'm mostly always like a week early!! Is their something wrong with me?Period Problems!?
Probably not. During the first year of your period is "normal" to have this problems, that is why some gynecologist prescribe bith control pill, to "regulate" your hormones and periods. You might want to try that. But. this doesn't mean that you are going to have sex, ok? ;-)
Everyone is different. Talk to your doctor
