I work at Target and have been seeing the DivaCup for sometime now and did some research. I started the first day of my cycle 2 days ago and decided to finally pick the cup up. I had no issue inserting the cup. I ran my finger along the rim of the cup once it was in to make sure it was completely open. It doesn't leak when I am at home, but I do have issues with some minor leaking when I'm at work. Enough that I need a pantyliner. I don't know what the issue is. I move a lot. Picking up boxes, climbing ladders, etc. Is there something I'm doing wrong? I don't know if I'm having an issue with the shape of the cup when I'm being super active.
