forgotten Tampons in the abyss?

I feel super stupid but I had notice my vagina was spotting a lot longer after my period and it was weird and had a horrible smell and I couldn't figure out what was wrong. So I started cleaning it with summer <a href="">eve</a> and it wasn't helping with the smell. So I just kept spraying water up there trying to clean it best I could. And today in the shower I felt like a tampon cord but I thought it was just a hair that had fallen out but it was a tampon. Just to help me feel a little better has anyone else ever left a tampon up there and forgotten about it and couldn't feel it?
