toxic shock syndrome?

hey guys so last night i was starting to get really bad cramps to the point where i couldn't walk and was curled over. I've never had cramps like that before but I just figured i was ending my period. well later in the night i started to get really cold but my body was warm. Took my temp and i have a 100.8 fever. Everything kept getting worse and i felt nauseous everytime i turned so i decided to take my tampon out which hadn't been in that long, but instantly i felt somewhat better. I still have a bad fever and i still have some bad cramps. I've never felt like this before. could this be tss? Anyone have any tips or advice?
