I've been using the Diva Cup for years with no problems. But I have noticed that when I empty the cup, there is usually a layer of clear-to-yellowish fluid sitting on top of the blood in the cup. It's often a thick layer, like 1/4 to 1/3 of the contents of the cup. I'm wondering if this is just blood that has separated into layers of plasma/red blood cells/whatever, or if there is something else going on, like if this is a sign of a urinary fistula or something else.
Maybe it was always like this, and I just didn't know, because I used to use a Keeper so I couldn't see the contents like I can in the Diva Cup.
Also I guess I should mention that my period blood seems to be super thin for the last year or two--it's almost watery and gets everywhere, not thick and goopy like y'all are saying in your posts.
So, does anyone else see a layer of clear or yellowish fluid sitting on top of the blood when dumping a menstrual cup?
