I have been having major problems my Diva Cup slipping down and partially out (this is including the base of the cup part and not just the tip) when I run (I train for and run marathons regularly so this definitely won't do) and am wondering if anyone else has had this same issue and if turning it inside out helped. Also, sometimes when I go to the bathroom it slides too far down. A lot of times I have to take it completely out after going to the bathroom and reinserting just to get it back in there. This is one of the main reasons I wanted to leave tampons behind--not having to change every time. Does anyone have this issue? I am on my third day and am so fed up I am about to call it quits. Any suggestions on how to keep it in place at all times, not just when I am sitting still or standing?
