First, be calm. I was 10 years old when I got it but there I have friends who got it at age 15.
The symptoms you are having most likely mean it'll come soon. I would say, wear pantiliners regularly and when it comes, put a pad on (always keeps some with you). Then, you'll be able to judge if it is heavy, lift, etc. and buy what you need. Secret121's tip about the green tea is really good and I would drink tea or anything calming during your period just to help with the pain and keep you as comfortable as possible.
You definitly don't want to get your period... and I'm not going to judge you for this but even though you don't get along with your mom, this is something that she should understand and be willing to help you with. You can always try to talk to you her about it.
Good luck chica!
