So basically, I've been finding brownish type "discharge" in my underwear. I've been looking all over google for what it is. I am 13 and have had my period for about a year now. I don't think it is my period though, when I first saw it I thought it was normal and put a tampon, then four hours later I take it out and see nothing. And then when I wear a pad it's always covered. I am very confused.
