Anyway, here's my question. Last week, my cup did not leak at all. It also did not leak all day yesterday or last night. I cleaned and reinserted it this morning, and after a few hours, I noticed I had leaked a little. So I went to the bathroom to double check my seal even though I check it when I first put it in and it was fine. It still felt ok so I left it, but then I had blood all over my hand. So I took it out. There was a little blood inside, but mostly it was just covered in blood on the outside.
So what happened? And how can I keep it from happening again? I have not been able to get it in very deep, so the base of the cup sits right at the entrance every time I use it.
