Hi there, I got a Diva Cup less than a week ago. I've got the hang of insertion & removal, but today & yesterday I've noticed it's poking into me and hurting a bit at times. The tip is just inside me and pokes at the tissue just above my opening. I took it out last night to give my bits a rest. I've got it back in today and had to adjust it a few times to avoid the poking. How can I avoid this? Obviously it's not always convenient to adjust it. Should I push it in a little further? If I try to pull it out a little so the tip is out (& therefore can't poke the inside of me) it just goes back in. Is this the situation that motivates people to trim the tip? If I trim it, is the 1-year guarantee void?
