Weird symptoms-anybody have similar?

I want to start by saying I am NOT pregnant. But within the last couple weeks I have noticed that I started burping excessively & having a ton of trapped gas…the trapped gas doesn’t hurt me at all more like discomfort because it wants to come out but cannot. I am not constipated and just feeling depleted. Can you have trapped gas but no pain associated? I’m not even bloated really.

I am seeing my doctor in a few weeks.
