Toxic shock syndrome ??

Okay, TMI and please be kind

I accidentally left a dryish tampon in for 18 hours. I went to the bathroom because I was experiencing really bad stomach pains not like period cramps just like a sharp almost burning pain and found the tampon. It was completely dry other than some discharge and now my stomach feels really tight and I’m nauseous. Does this sound like TSS? I have three little kids and I exclusively breastfeed my youngest so I don’t wanna have to go in the er if possible.
