I just went to put my large MeLuna in and when I slid the edge of the fold in I bumped into something. You guessed it, my cervix. Now I know I have a low cervix to begin with, but GEEZ!!! It's literally RIGHT THERE at the opening, at most .5", possibly as little as .25" in. How very, very strange. It made getting the cup in (and around instead of beside the cervix)... interesting. LOL!
I just wanted to share my frustration and amusement. :-)
