I can't decide and i don't know....?

I would totally recommend using tampons girl. I used to use pads until one day i thought, why not. I've never used pads since. They are cleaner by far and when you use them, it doesn't even seem like you are on your period. So i would say give them a try. As for the disease you are on about, that is very rare and as long as you make sure you change the tampons regularly, then you will be fine. Don't rule them out because of that though.
