Hi, Today I Went Shopping And Decided To Go The

Hi, today I went shopping and decided to go the toilet. once I sat down and urinated I discovered that there was no toilet paper. in desperate measures j used a piece of toilet paper that looked clean from the unisex bathroom floor. it was dry. at the time I wasn't thinking but now it's all I can think about. could I be pregnant? could I contract a vaginal infection? please answer soon
