I have a DivaCup, and I'm having trouble with removal. Every time I remove it, I have to squeeze it a bit to make it, er, "fit," and this means that some of the blood gets pushed out of the cup and I end up leaking it out later. The other problem is that even with squeezing it removal is still painful and by the second or third day of using the cup I get really sore. Any ideas for making this easier? Thanks!
