Do what is your personality and how others see you. There isn't any reason to hide your true self for your wedding day. You feel comfortable to wear the nose ring, then do so. Your husband doesn't need to see you any different as you are.
I love a good piecing so I say go for it! Plus in my experience nose piercings fill in FAST. I'm talking one day I lost my nose ring and didn't wear it for maybe 10-12 hours and I couldn't get it back in. That's the only reason I don't have my nose pierced anymore, I've had it done twice and I don't want that pain again lol!
