First time cup user

I tried the menstrual cup for the first time today. It honestly hurt when i put it in there. But that wasn’t all. I counldn’t get it out. It look me multiple positions and 3 hours to finally get it out and it hurt like hell. I did pinch the bottom part to get rid of suction but everytime i did that i lost the grip and the cup became even more tighter. And my muscles are soo damn tight that I couldn’t even get one finger in there to pinch the cup. I’ve tried relaxing but my muscles are too tight in general i guess.

My muscles are still sore after removing it like i can feel the soreness. I really want to use it again but i can’t Go through the pain 😭. To make it all worse I have septate vagina and low cervix.

And im scared if this will lead to prolapse as my muscles feel weird now.
