Tampons

Ok so I have decided to try out tarpons because I want to go swimming for the 4th of July. But the problem, well with idk if it is a problem, is that these past couple days with tampons have kinda been strange. I feel really light headed and kinda dizzy when I use tampons. Is this normal? I get kinda scared and bail because I have heard of I think it’s like Toxic Shock Syndrome. Something like that. But idk. What do you guys think? Does this happen to you too?
