Also, it tends to leak a lot, and I've tried finding my cervix but can never find it, so I assumed it's pretty high up but I'm still leaking! The way I put it in is I use the fold I mentioned above, make sure it's open by running a finger along the edge, twist it to make double sure, and sometimes push it up so the stem isn't poking me.
I don't consider my flow heavy, but I don't really know how to tell how heavy your flow is. I weigh about 90 lbs, so I don't think it would be too heavy.
Please help, I really don't want to go back to using pads and tampons!
Just survived my first full leak-free week with the cup! SOOO HAPPY!!!!!! Thank you to all of you for your tips. For anyone who needs help with this sort of problem, all I had to do was tilt the cup toward my left and let it open pretty early on, and then it would kind of do its own thing and get in the right place. I also used the punch-down fold and cut the stem almost all the way off (but I think even if I cut it off completely I'd still be able to get it out, since I don't really use it anyway).
When I was using the punch-down fold, I found that if I don't punch it down all the way, it opens quite easily. Just a little tip.
Again, thanks for all the help!
