Tampon issue!

Ellie

I started using tampons last month and they feel a lot cleaner than pads. But I've noticed that I'll fill up one side of the tampon and then it'll leak past and onto the string so I have to change it. then I'll take it out and still see white patches.. I'm using playtex sport super and regular and also a target brand light tampon but they all do this! (Not every single time, but a lot) This morning I had to change my super tampon every 30 minutes until I gave up and switched to a pad (which feels really gross.) I really want to figure out how to make tampons work for me but idk what brand to buy! Last month I could wear a playtex sport regular for 2-3 hours on day 2 without leaking and today I can't even wear a playtex sport super for an hour bc for me, some periods are heavier than others. should I try tampax active? Tampax pearl? advice please! I'm 14 yrs old btw. (P.s. They feel comfy while in so I think they're in correctly)
