New issue for long time cup user

I’ve been wearing a menstrual cup years. I have the regular size Saalt cup. I’ve never had issues with it until recently. During my period in November I went to take it out and realized my cervix had dropped down and was sitting inside my cup. My gynecologist said it’s normal for your cervix to lower during your period but mine had never done that before. The next day my cervix lowered again and then took my cup back up with it. It goes in totally normal, but (for my last three periods) almost every time I go to take it out I find that my cervix is sitting inside the cup. It’s difficult/ a little painful to get it off. It seals around my cervix and I have to squeeze the lip of the cup to push my cervix out of it. Has anyone else had this issue? Do I need to try out a different type/ size cup?
