The tale of the forgotten tampon

Somehow towards the end of my period a tampon got pushed up so that I didn't see a string and couldn't feel it. So I simply forgot it was there. We my bf and I had sex he complained of feeling something that bothered him, but i he couldn't describe it and it didn't seem a big deal so I forgot about it. Then I started to get a really aweful foul smell coming from my vagina, also had no idea why as everything felt ok down there. After a few days it got so bad that I googled looking for answers. Finally figured out that I might have a lost tampon stuck up there. Yep. Quite an expierence pulling that gross thing out. Might need to stick to pads from now on. So embarrassing!
