HELP! LOST TAMPON!?!?!?

Okay, so about half an hour ago, i put a tampon in, but it wasnt inserted right, so i took it out & chucked it away. Then, i put another in but it was an applicator one, and the applicator fell of, which just left the tampon in the tube. So, i put the string in a ball thing, and put the applicatior back on, which ment the string wasnt hanging down. i put the tampon in, not thinking about the string and i looked and there was no string! i got scared and wondered if it had fell out on the floor, i couldnt find it. so, i didnt want to use my fingers, so i 'inserted' this CLEAN end of a pen (i washed it before throughely) and it went all the way in, but i didnt insert the actual pen nib lol. im starting to doubt if i even put one in, but im sure i did. please help! im not going to the doctor and i dont want to use my fingers bcus im only 13! HELP!
