I did the C fold and got it in without a problem! I was so shocked! I even got up and did a little dance--it didn't feel like anything in there. I figured I would try taking it out just to make sure I got the hang of it. That kinda freaked me out for a second because of the suction--but I pinched the bottom of it and it released. It didn't hurt or anything! I tried it a second time just to make sure I had the hang of it--it was kinda funny because I heard it suctioning as it went it. It wheezed.
Now, I'm going to bed with it in. I don't have anything for back-up since I usually use tampons and don't have a problem with them, so I hope this doesn't leak. :/ I'm going to put a towel on the bed just in case. I think I have the suction right since I gently tugged on it and it didn't give. I even left the entire stem on. If it doesn't bother me, I'm just going to leave it as-is. We'll see tomorrow.
I don't think I've ever been this excited about a period---not even when I was 13!
