How do you get a stuck tampon out (safely!!!)?

I know that this is super embarrassing, but I went to take out my tampon and the string wasn't there. I've concluded my tampon has gone on a quest of its own and I need to get it out before I have a serious problem. I squatted, put my finger inside in search of this missing tampon (I know it's in there), pushed like when doing a bowel movement, but nothing. I was thinking of running some water for a bath and maybe soaking in that and hoping it comes out, but I've read that tampons don't just "come out". If this doesn't come out soon, I will go get medical assistance, but for now, have any of you ladies out there had this problem? How did you solve it? Sorry, I know it's a bit awkward!
