Menstrual Cup issues and questions!!!

Bre

In serious need of advice. This is my first period of trying out my cup. When I have the cup in I feel a lot of pressure but Idk if it might be because I’m cramping. How can you tell it’s sealed?

I don’t feel it when I have it in I just feel pressure in my uterus.

I know I will get this down soon but I just wanted to know is all. Thank you for the advice and answers in advance.
