about 4 hours ago i had to go to the bathroom extremely bad(bowel movement), i had to go in a public restroom that was extremely dirty and disgusting, after i went i wiped and was done, and then as i was leaving i saw that the toilet paper had a red stain on it that had gone through the roll of the toilet paper to each piece(idk how far through it went) , it appeared to be blood and appeared to be dry but idk if it was or not or how long that it was there. Is there any possibilty that i could have gotten hiv or any stds or diseases from using toilet paper that had blood on it? to my knowledge i have no cuts but you never know. what are my risks if the blood was fairly new and just put there? also do i have a risk if it was on my hands and i touched my lip or a cut or anything? please help im extremely worried and my body is already tingling and im getting sick.
