I've used a Keeper for around 10 years and I always had a bit of light leaking but I just use light cloth pads as a backup and I'm cool with that.
I had a baby two years ago and I finally feel comfortable enough with myself to try the cup again. I tried my old Keeper but it was sitting too low and it's been long enough that it needed to be replaced anyway, so I got a size 2 Divacup because that's what the local eco store carries and I figured it'd be similar to the Keeper.
The size seems good, it sits so none of it is sticking out. When I first had it in, I felt sort of crampy but I seem to have figured that part out by wiggling it a bit into a comfortable position, but my big problem is that it leaks like it's not even there. My pad has real blood on it, not just light spotting from leaks. The cup is bloody on the outside and has very little on the inside, though it does have some. I do not have a very heavy flow right now, so it's not that it's being overwhelmed somehow.
Are there any tricks I can try or reasons why it would leak so much? Thanks very much!
