Okay so, your body changes a lot during puberty, and these changes are like your body's way of sending you signals. One of the biggest signs is breast development, because most girls get their period about two to three years after their breasts start growing. Another super common sign is vaginal discharge, which is this clear or whitish stuff you might see in your underwear. It usually starts about six months to a year before your first period, and it's totally normal and healthy.

You might also have a big growth spurt before your period, like you suddenly feel taller. All these things together can give you a good idea that it's getting closer. And knowing what to expect can make it way less surprising, which is good!
