Constantly crying & uncomfortable 2 week old

Exclusively pumping she eats good and wet diapers are regular. Very gassy and uncomfortable 24/7 when she’s not sleeping she’s grunting crying or fussy won’t let us put her down. I don’t eat dairy and my diet is clean It has to be my milk we burp her and she belches every time … then right back fussy and squirming uncomfortable we literally pay her back and rub her tummy 95% of the time she’s away until she falls asleep. This is been happening since day 2… in the hospital the next day after she was born. And in the hospital she took Similac since my milk wasn’t in. help!!! Should I call pediatrician? Should I switch from pumping to a gentle formula?? Idk
