I went through size charts, I scratched my head, and like so many of us I didn't really know where to begin. I decided to go middle of the road - middle height, middle width, and see how it worked. I thought as long as I had *A* cup I could figure out what worked, and what didn't, and go from there if my initial choice just wasn't a good fit. I ended up getting a Model 1 Miacup (which I haven't really seen promoted by the users here, and wondered if there was a reason, or there were just other brands people used more/were comfortable with?).
I emptied it at least twice a day. On my heaviest day, it was half full, so I think the size is good :) I can't feel it inside, and it doesn't migrate in too deeply (I can reach the base after only a little bearing down, and squeeze between two fingers to break the seal). I did have some leaking the first real day of my period, when I first woke up - but I believe that was due to the cup not opening all the way, and therefore the seal wasn't created. I was able to empty in public restrooms no problems! \o/
But it's not perfect. I still find sometimes I have to insert it a couple times before I can get it to fully open inside. I seem to have better luck when I don't fold all of it over, and leave a pocket of air in the base to help it pop open? If anyone has any suggestions on something that might work better (as this did not work 100% of the time) it would be much appreciated!!
I wanted to thank this community, and especially those who are also members of vaginapagina as without you I would never have discovered cups!!! I couldn't stand having diapers (pads) on, and was never comfortable with having bleach-filled tampons in all the time, but couldn't find a better alternative! And now I never have to worry about having enough tampons on me to survive a day :D
