Now, I got my lovely Lunette shortly after New Years, while I was still on my period, so I tried it out (after faithfully boiling it and cleaning it, as per the instructions). The first time, I got the cup in just fine, I even got most of the stem in, but I could still feel it(the stem) poking out a bit. I figured I would just try it really quickly while I showered, just for a sense of how to get it in, and how long I might be able to leave it in based on my bleeding, and whether or not I needed to trim the stem, and if so, about how much. So, after my shower, I popped it out, cleaned it up, and tried to put it back in. It wouldn't go all the way in before I could feel it bumping my cervix, and once I tried to push it in further, trying to angle it a bit differently, there was this almost pinching sort of pain, the sort where my main thought was 'GET IT OUT NOW, THIS IS NOT FUN ANYMORE'.
Every time since then, I can't get the cup in all the way before it hits my cervix, and then the painful pinching, and it needs to come out. I even trimmed the stem completely off, just for less length. I just tried again tonight (I'm pretty sure I just caught the VERY beginning of my period tonight) and I'm still running into the same problem. I even tried laying down and (again, potential tmi, sorry) masturbating to help, not only by providing natural lube to ease the cup in more easily, and to relax me even more (because what's more relaxing than orgasm? XD), but to also get my cervix to back off, but it still didn't work.
Is there some secret special angle the cup needs to go in at that I managed to find the first time, but am now missing? Is it just that I need a shorter cup?
