I was sceptical that I would 'fit' any cup, let alone the first one I tried. I can only sometimes get tampons to sit right, and I wasn't overly full of confidence.
First cycle and I'm loving the switch! Removal was very tricky at first (took me a solid hour!) but some googling and patience worked wonders. No leaks after 12 hours, don't feel a thing, such a fantastic product! Highly recommended!!
Note: I got the 'low cervix' option because I can feel my cervix halfway between my 1st and 2nd knuckles. I can find the stem of the cup easily, but I can't feel it at all, and apart from the usual cramps I could easily forget I even had my period!
