I am 20 years old, and I bought my small Lunette a little over a year ago. At first I was very successful, but then I started to have problems with getting the cup to seal correctly. I used a toothpick to make the holes at the top a little bigger, hoping that would make it easier to get a good seal. I haven't had any luck and it seems like my muscles are strong and tend to push the cup almost completely out. I had to stop using my cup and go back to tampons which I absolutely hate because they give me severe headaches. I was considering buying a new cup all together, but I am not really sure what direction to go. I think a Meluna might be a good option, but I know it is difficult to get them in the US right now. I would appreciate any advice because I really would love to start using a cup again. As a side note, I also got a bacterial infection and I am afraid it may have come from the cup and I am worried about making sure it is sterile enough to continue using without getting the infection again, which is another reason I was considering getting a new cup.
