I'm sure this gets asked a lot, so I do apologize.

I am mostly past my health anxiety, not so much my generalized anxiety, but most months I get a fear of TSS for some reason. I do have to use tampons early on in my period, and even though I'm very careful about using the right size and not leaving them in for too long, sooner or later I start getting nervous about this.

Today I had one in for maybe 8 1/2 hours (recommended time is 8 hours). Logically, I'm telling myself that I didn't leave it in for too long, etc. Logically I'm telling myself that TSS is very rare. Illogically, I have a headache (have had once since noon) and I rarely get headaches that aren't migraines, which this one isn't. I'm a little sleepy, now I'm starting to feel just generally achy. I know that it's mental, but it's hard to ignore.

Any reassurance, or personal experiences?
