ANDY'S ANSWER: Well, it's probably time to have a talk with your mother, because it sounds like you need some pantiliners for now and also some thicker pads for later when your period becomes heavier. However, it's quite likely that she has some in the bathroom already. A pantiliner is a very thin pad that has a plastic liner to keep liquid from seeping through to your panties. It has a sticky back that sticks the liner to the the inside of your underwear so that the pad faces up and absorbs the blood and keeps your underwear clean.
