baby threw up advice please !!

So yesterday after feeding baby I put him on my bed to sleep since his inclined Rock and okay sleeper was being cleaned. After a few min he woke up so I picked him up and he threw up all he ate. I burped him again and he was showing cues that he was hungry so I fed him again. He threw up again ☹️ so I decided maybe it was something I ate that wasn't settleing well with his stomach so I stopped using that breast milk that I had pumped. The rest of the day was fine . He had an extremely fussy afternoon after that happened. Today in the afternoon he got fussy again while at my inlaws house . It was loud so I took him to a room and tried to calm him. He seemed to want comfort so he ate his milk from the bottle ( I pumped) and then started searching for the boob so I feed him breast . I assume I over feed him because he ended up fussing more And threw up again.  He's crying and yelling when he randomly . What could be wrong :( I'm trying to get a hold of the pediatrician. Should I continue to feed him again ? He is known to get gas and colic but this is different
