I went to a concert and dropped toilet paper on the floor and wiped myself with it after peeing, can i can a vaginal infection from this? i am very worried since the floor i am assuming at a concert venue is probably very dirty?

It is important that never use any thing lying on floor at public places . You do not know the bacterial or viral infection contaminated on the toilet paper. It was essential that even if you used it , you cold have washed your body part to reduce the chance of infection or to minimize the risk . Now just wait and if any symptoms starts , must see your OBGYN
