HELP 13 DONT KNOW WHAT TO DO

Hey girls I need help. So I’m thirteen never engaged in any sexual contact what’s so ever and don’t put any products down there and I don’t masturbate only done it like once and change pad regularly when on my period and wear pantie liners and change those regularly as well. But for a a month or two. I’ve been getting a lot of discharge and I can always feel it when I’m walking or sitting or doing anything. And if I don’t wear a pantie liner it will go through onto my clothes. And it has a strong odour but I don’t think it smells that fishy. Never used a tampon either and not on any medication. HELP PLEASE I DONT KNOW WHAT TO DO. Any suggestions on what it is and what to do. Thx luv ya guys
