Don’t panic. It’s really hard to “lose” anything as big as a tampon inside your vagina. Tampons are held in place by the walls of your vagina, and there’s nowhere beyond your vagina for the tampon to go. Your vagina ends at the opening of your cervix, and a tampon can’t go beyond that.
Now, let’s get it out. Lie down, take a few deep breaths to relax, and reach inside your vagina with a clean finger. Feel around for the tampon string. If you feel it, gently tug or pull the string with two fingers. Some tampons don’t have strings, but your vagina is only about two to four inches long (though it can stretch to be a lot longer to accommodate vaginal intercourse or having a baby), so chances are, if a tampon is in there, you’ll be able to feel it.
Your tampon might feel slippery and hard to grab. If you feel the tampon but can’t pull it out yourself, a nurse or doctor might have to step in. You can always contact your local Planned Parenthood health center for help.
