Weird breathing issue...anyone?

Started noticing a “stutter” in my breathing at the top of my deep breath yesterday. The only way I can describe it is like when you’re uncontrollably crying hard and your breath “catches” or stutters when trying to inhale. I’m assuming it’s an autonomic thing with the diaphragm? Anyone else experience this when taking deep breaths? I seem to be fine if I force a yawn...and it doesn’t happen with every deep breath. At first, I thought it was a GERD thing, because I do have that and my stomach was not feeling great last night...but then I noticed it a bit this morning, too.
