TSS HELP

J
I left my tampon in for almost 9 hours, 7am - 3:45 pm
I use a regular tampon and its absorbency isn't too high so there's some blood on the string
Anyways I took a nap for 2 hours but I was laying on my stomach, I also haven't had any bowel movements since 2 days ago. I'm having slight cramps but this could be due to how I slept (this always happens) but I'm just concerned because of the tampon. Should I be any more worried? Please help!!
