Gassy breastfed baby

Ophelia

My 5 week old is so gassy and uncomfortable all the time. I breastfeed and feed pumped milk (no formula). We burp her but she just cried everytime she’s awake. It’s not colic because it seems to be directly linked to gas. Anyone else experience this and know what could be going on? She also spits up quite a bit. I feel so bad for her.
