worried about tss (left tampon in/already sick from before)?

I've had a super bad cold/cough/flu since last thursday, and I got my period on saturday. i'm usually very irregular, and this one was unusually heavy, so i've been using regular/super/superplus tampons. this morning i put in a tampon (either reg or super i cant remember) at 9:30ishh. At 1ish i went to change tampon/pad (im at a 10 day athletic competition so i'm using both because im outside all day and cant leak on uniform). I was in a rush and completely forgot to take out the tampon after i changed my pad, but i put a new one in (superplus aborb.). I put in another at 4ish i took it out (the second one), and i did the same at 7ish. When i got back at 11:30pm i realized what i did and took both out. It didn't look terrible and i dont feel any different, but now im concerned about tss. I have had a cold/flu since before i even got my period, i left one in for 14+ hours, and ive been using super and superplus tampons. How can i differentiate between the symptoms, any help is appreciated. thank you.i also have a sunburn, so the whole rash symptom would be hard to recognize.
