So all day my tampons have been falling out. To put it bluntly. I'm using the exact same kind of tampons I have always used and never had any problems with before, but they will not stay up there. I do not understand, and frankly it's really frustrating. And kind of gross. I checked out the insides as best I could and they all seem normal, and I really doubt that my vagina has expanded any (especially since yesterday) so... Any ideas as to what the crap is going on? Does this happen to anyone else?
