This is quite embarrassing, but I remember putting a tampon in and my boyfriend and I were fooling around and I forgot about the tampon. When I went to the bathroom, I realised that I had one in but the string was gone and now I'm not sure what to do. People have told me that when it's full it will just come out on its own but I'm not sure if that's true? It's been in for over 24 hours now. Please help!
