let tampon in too long

over the weekend i left my tampon in for almost a day and i just forgot it was there. there wasn’t much blood since it was my last day on my period but a day after i start noticing this bad smell but i genuinely didn’t think it was me until today when i noticed it is me. tmi but i did taste myself a little because i know how its supposed to be but it is definitely not the same. there’s nothinh different besides that. but im just wondering what i can do besides going to the doctors office. i cant go right now so please anything helps
