Going from a girl to a woman is quite a scary progress and it is actually normal to be scared. The good news is, we all survive it and you will too. Discharge is the clear or white gooey stuff that you may find in your underwear or when you wipe. It is there to keep you healthy and is completely normal. You can wear a breathable liner to keep you and your underwear fresh. Many girls notice that they start getting discharge before they get their period. It is normal to get your period between 11 and 16 years old so yours can come at any time. I'm glad you are well prepared with pads and tampons. If you haven't practiced with a tampon yet, and you get your periods at school, start with a pad. If you feel comfortable using tampons then go for it. Both are fine.
