I would like to ask if anyone else has similar problems than I do. I have used my Lunette 1 and 2 (nowadays only the size 1) for 7 years now and been having the same problem for a while now. My cervix is extremely low and it takes about half of the space of the cup. When I'm on my period, my cervix is right there when I put my finger inside. If I squat all the way down, the cervix almost comes out. My vaginal opening gets pretty sore because the cup keeps it a bit open and the tip scratches the lips sometimes. I also have to empty it pretty often because there isn't that much room for blood.
I've recently read about Merula and Femmycycle (low-cervix or teen) and other shorter cups and will most definitely try either one of the mentioned, propably Meruna because it's easier to get.
Another thing that I would really need help for, is how to solve the problem of going upside down while wearing a cup on my period. I do handstands, acroyoga and partner acrobatics and I have to use a tampon on those days, because the cup leaks. I am an experienced user with my Lunette so it's not possible it isn't put there properly. I also empty it right before I train. In every position with a possibility for vagina farts, there is also a possibility for blood catastrophe after I come back to standing. I don't now if it is the vaginal muscles that push the cup to fold or what happens, but all the blood runs out and I'm in trouble. Has anyone found a solution (cup) for this problem?
Otherwise I've had no problems with cups. Sometimes it feels like I had to pee but that's not a big problem. I am quite sensitive but it's been alright with Lunette even though it's quite firm.
