What does a peptic ulcer feel like?

I’ve had a lot of symptoms that line up with this but curious what it’s like. I have constant acid reflux (even with high does anti acids) stomach pain above belly button, tender to touch and dull ache on and off. Constant nausea for several weeks now and acid reflux for a little bit longer. Just asking because I’ve been waiting for my drs appointment and testing for weeks now and still don’t see anyone till Tuesday.
