I'm not sure if I am getting suction or not. I just started using my cup today. It's not leaking crazy but it is leaking a tiny bit. It wasn't over flown or anything so that wasn't the issue. I BELIEVE my cup opens up before i get it in the spot it needs to be in. I thought i heard the suction but i wasn't sure. Any tips? I have the lunette size 1. I am not a virgin but i have strong vaginal muscle so I got the smaller one as my first. I normally only use regular sized tampons and I can leave them in for a long time before they are full. Thanks!
