It's my first day wearing a menstrual cup and not even an hour passes and I keep leaking. I insert it with no problem and I feel like the vaccum is created, but somehow it keeps leaking. I keep having to go to the bathroom because I notice I keep leaking. I read about taking consideration of the cervix height and I measured it and it seems like I can barely touch it with my middle finger, which I understand means my cervix is pretty high. Is it possible that the cup is simply too low? I try pushing it in as far as I can until I feel a little pain but nothing seems to be working. My cup looks like the classic ones, and if it's helpful the measurements are 9.4x5.8x4.4cm (I live in Italy so the measurements are in cm sorry about that.)

Thank you, I'd really appreciate some insight.
