IUD and Diva Cup long term

This is more of a question and a concern, ill drop my story here, but my main question is if i'm EXTREMELY careful, can I still use the diva cup? I despise pads and tampons with all of my being:

Due to the current political climate in America, I'm looking at getting a paragard IUD and have an appointment scheduled with my obgyn that I can cancel if I change my mind. My medications for the procedure will be Diazepam, Ibuprofen, Acetaminophin, Misoprostol, and laughing gas. I never wanted birth control to begin with since i'm in a monogamous long-distance relationship and he's fine wearing condoms, but the political climate has me too nervous now.

Hormonal BC was NOT an option for me for mental health reasons. I guess i'm looking for other people's experiences with paragard and they didn't have any other women's health concerns. Lots of horror stories about iuds come from people who have endo/pcos, irregular periods, given birth, experienced sexual trauma, had an IUD before, etc.

My OBGYN is wonderful and walked me through every step and answered every question, but I don't know if I have the energy to go elsewhere and fight insurance for anesthetic.
