Gassy baby

FTM here. My daughter is 2 1/2 weeks old and is very gassy. She has a dirty diaper maybe every other day. I do pump milk for her but I do not produce alot so I supplement with formula (maybe 1 bottle, the most 2 of formula). I did cut back on gassy foods from my diet, drink tons of water but it seems like nothing is helping. You can tell she's uncomfortable. What else can I do to help her? The pediatrician recommended that I give Mylicon drops and gripe water but they seem to only help for a very short period. Should I supplement with the Enfamil Gentlease instead of the Similac formula? Does that help?

I've also tried tummy massages, moving her legs in a bicycle motion to help but nothing gives.

And I do pump every 2 hours and I still do not produce enough.
