So I've finally done the research and got myself a cup. Today I get to use it for the first time which made the arrival of AF when TTC a little less disappointing. I did my research first about how to insert it (which seemed challenging due to its size) to twist once its in and to push it in plenty. I was told the first few times would be uncomfortable and I would notice it. That's why I'm worried. Although it was not pleasant to insert and there was some scratching/pinching of my nails (ouch) I can't even feel that it is there. Should I? I'm also worried it hasn't popped open but have no idea how I can tell :/ Any advice would be much appreciated!
