Menstrual cup help

I never used a cup before I had my baby. I used it for the first post partum cycle and it was incredibly painful to remove. I watched a bunch of YouTube videos and figured out the problem and now it's much better. Second post partum cycle and it's still a little tender but not painful. My problem is that everything is low inside and so even after I cut the tail of the cup off the end of the cup still sticks out and it is uncomfortable and leaves me sore by the end of the day. Any tips or tricks?

What's your favorite cup?
