I have a couple of questions about the Diva Cup. I bought one today and I've been following the instructions but I'm not sure if I'm doing something wrong or not but is it supposed to sit so low? The bottom of it is just inside my vaginal opening and it won't go in any further. I cut off the tip to see if that helps because it was irritating me. I also feel like it's going to come out when I urinate or have a bowel movement. It definitely moves lower when using the toliet. I cannot feel my cervix when I try to find it but I'm not exactly a skinny woman, therefore I cannot reach that far into my vagina in the first place. Any suggestions? Or am I doing this correctly?
