I am a long time tampon user. I recently bought myself a Diva Cup & I love the concept, but am struggling to use it properly. I can insert easily, but am struggling terribly with getting it to open up once inside. I realized this was going on because I was having so many leakage issues. I knew something wasn't right & when I feel inside I can feel that it's not open. The instructions say to rotate or spin it, but it won't do that. Sometimes I can push it up as far as I can & then bear down as I pull it down & that will work, but it doesn't always work & I can't always stay in the bathroom for 20 plus minutes fighting with my cup. I've also tried inserting a finger alongside it to give it space to open, but that doesn't always work either. I've only gone through one period using it, but I saw no improvement in getting it to open during those days. I am 39 & had a c-section 3 years ago. I am using model 2. Can anyone help??
