So I found out about menstrual cups and thought they were an awesome thing and am now the proud owner of a Diva Cup. I bought the smaller size, since I'm still a virgin and a pretty petite person. My period started today and I got all excited about using my cup, only to discover that I can't seem to fit it 'up there'. I got really frustrated and started to do some exploration with my fingers. Turns out I can't even fit two fingers past what I assume is my pubic bone. Is this some sort of anatomical anomaly? I did my dang best to relax and work my fingers around, but I just don't see how anything is supposed to fit past there. Help!
