text: when do you think my period will start so i can get an idea of when to be prepared? plzz im 13 andi see discharge at least 5 days a week but i have no cramping prblems whatsoever  plz help me with this it sounds like it will be starting very soon, and you shouldn't go by whether you are getting cramps or not.  some women don't get them around/during their periods ever, while some do.  your best bet would be talking to your mom about getting you some panty liners, so when you start, you don't leak and get an embarassing stain.  i'm sure she'll be glad to help you out.
