Irritated urethra from tampon?

I’m half way through my period.

Usually when I have a tampon in I pull the string up between my vagina lips. (Is that weird?) I always have. Just so it’s out of the way.

Well this week. I noticed pain about my vagina. Looked with a mirror and it looks like my urethra is all red, a little swollen and sensitive.

Doesn’t hurt when I pee just to the touch.

Think this is from the tampon string or some kind of uti?

Thanks y’all
