Help a FTM out!

Hey all, feeding question... LO is 7 weeks, she eats 3-4 ounces every 3-4 hours... she’s on Enfamil NeuroPro if that matters.... however I feel like she is still hungry after feeds like her formula just isn’t dense enough if that makes sense.. I know people are going to say “give her more” but her stomach is literally full and popped out like she possibly couldn’t fit anymore in there and I even tried giving her an additional ounce once but it just came back up as I stated it’s just too much for her belly... any recommendations?

EDIT: let me clarify, she’s not gassy, doesn’t need burped... she’s giving me actual feeding cues as she’s still hungry... so my real question is, what formula is more dense/filling?
