My body will push out the cup when it gets full-ish. (Often just under halfway full.) I have to run to change it before it comes out all the way and spills.
During heavy days, this can happen several times in an hour as one clot will fill the cup to between the 15 mL and 30 mL lines. Obviously this is a problem if I need to leave home or meet with a client, etc.
If I'm reasonably active, the cup will often settle into a position with half of it extruding outside of the vaginal opening.
I'm using a L DivaCup. I have children and I'm in my late 30s.
My cervix is average, I think. I can reach it but it doesn't seem "low" in the way that I hear that term used in this forum.
I'm already using one of the largest cups. I'm considering trying a SuperJennie because it seems wider at the base, but I'm concerned because it's softer. Any other suggestions? I couldn't find any threads discussing this topic.
