Semi TMI first time use.. advice?

I took the put a cup in it quiz and chose a very soft/flexible/small cup. I think lena? Anyway, I am quite petite and have a low-mid cervix. The first time I tried to insert the cup was a huge fail. I couldnt get any fold right to stay folded until it was anywhere close to inserted, and things were just difficult in general. I decided the next time I would try with an addition of some lube. Well, I decided to try in the shower instead. It went a little better, but it was pretty uncomfortable/difficult, but I was able to hold the fold and get things a little more situated. The next thing, was getting it to pop open completely. I couldnt really get my fingers in there enough to kind of manually pop it open and I couldnt get any leverage to like twist it as suggested. Eventually somehow I got it to fully open and I definitely felt the suction, which became painful almost instantly so I'm thinking it did manage to suction to my cervix maybe? Because of the discomfort I wanted to remove because I didnt think I could really adjust it. When I was trying to squeeze the sides to break the suction it seemed like I had to get so far up there to get closer to the top to get it to break the suction which was super difficult too. Once I finally got it out, the pain I had felt lessened but stuck around for a little bit. I'm just really nervous to try again and i feel like it's not for me or maybe there is a bigger issue?

(Side note: other penetration is not typically painful for me and I was completely calm and relaxed going into this as I knew I would need to be and I have been very eager to try this whole thing out so I wasn't really so psyched out to do it.)
