Will stopping Metformin cause weight gain?

I have been on Metformin for years and recently stopped. After speaking with my doctor and wanting to be completely med free, I thought I'd really try and manage by diet & exercise. The doctor told me she didn't think there were studies regarding weight gain once you stop but I'm curious if this has happened to anyone else.
I haven't been perfect with my diet/exercise plan but I feel it's harder to lose the weight now. I'm lowcarbing and trying to eat mostly whole, clean foods. Nothing processed, etc.....

Has anyone else had this experience?

Thank you!
