Baby gas

Anyone recommend a product I can use for our little one? She gets air bubbles in her tummy so bad to the point she’s screaming for hours. I burp her every ounce she eats and she burps good, I’ve tried little remedies gripe water, mylocin, laying her down and bicycling her legs, holding her tummy, warm bath but nothing so far has seemed to work .. am I doing something wrong? Or not doing something I should be? She will be 7 weeks old tomorrow. Starting to get desperate at this point for her tummy and my sanity 😖
