My one nostril closes when I inhale, but the other one doesn't. Is this normal?

I haven't had anything done to my nose. Is it just the muscles of the nostrils that might differ a bit on each side, or should I be concerned? The nostril not contracting seems a little bigger than the other as well. I have a little snub nose. I'm considering getting rhinoplasty done in a few years time... Thank you for your time! :)
