My thoughts are that while a MeLuna Small is too small, everything else should be okay size wise. I've heard a little bit about Lunette's causing irritation, so I was considering steering clear, but could be convinced otherwise. I would appreciate any advice that anyone has to offer.
--- I decided to buy a M Meluna Soft Cup with a Ball stem from another MCer. Thanks for all the advice. I'll let you all know how it goes (given my period ever comes, as it's 3 weeks late about now)
