I need some serious help choosing a new cup. My cervix is very low and my LadyCup is far too long, even with the stem trimmed almost right off. I've read that the Meluna cups aren't made from silicone, and I would like a silicone one if possible. I'm so overwhelmed by all the brands and size charts. So could someone please tell me the shortest cups available. I've had two children and I'm 28 years old.
