Going from convex to regular

Silly question, but has anyone gone from a convex to a regular seal?

I gained some weight after surgery and my stoma only poked out about 1/4". I switched to a light convex and all was good until about a week ago. Now my bag seal fails from the barrier ring out. I have c extenders so they basically kept the bag on along with the barrier ring but the 1 1/2" area from the edge of the barrier ring out just does not stick more than a day.

I just put on a regular bag and noticed that my stoma now sticks out about a good 1/2" past the bad and barrier ring seals. I think I lost so much tummy fat that I do not need a convex anymore.

Anyone else have this issue with going back and forth from regular to convex based on belly fat?
