Should I get my retainer checked?

[John Smith]

Hello, I recently got my braces removed and have started wearing a clear retainer on my top teeth. However, recently my retainer seems to have gotten loose? To elaborate, my retainer doesn't move or fall out of place on its own (it stays on pretty well without any jiggle), but when I start to take it out (especially on the left side) it comes off very easily with very little resistance.

I'm not sure if this is fine or not and would like to know whether it would be a good idea to get an appointment with my orthodontist to get it replaced or something.

Thanks for your help!

P.S. If needed, I can, and will, offer any other information you might need regarding this situation.
