I recently purchased the Lily Cup size A. It was much easier and less painful to insert than the other cup I tried (I had the Lena sensitive and I found insertion and removal painful, but it was very comfortable once it was in), however after I had been wearing my Lily cup for a while, the cup turned itself crooked. The stem was digging into my vaginal wall, but the cup stayed sealed. It became uncomfortable after a while so I tried to nudge the cup into a more normal position, but it went back to the crooked position after about 20 minutes. I then removed the cup and emptied it and reinserted it, but after a few hours it went crooked again. The cup was still sealed perfectly every time it went crooked, but it was a bit uncomfortable to have the stem digging into my vaginal wall. I don’t really know that trimming the stem would help because for the few hours before it goes crooked, it is so comfortable. It always leaned towards the same side. I tried to insert the longer end of the cup toward my tailbone, as I’ve heard that works best for most people. Do you have any ideas as to what may be causing this or how to fix it?
