I have gone through this many times. It sometimes progresses up a bit to area around lower right ribs. It is a sign of light constipation for me.
(I do 47:1 so I am not afraid to eat a large serving of whipped cream for dessert if I feel like speeding my digestion up. I find it incredibly effective. Protip - add authentic vanilla extract, to take the taste to the next level 😋)
