Gassy baby

My daughter is one month old and three days ago started having issues with gas. She’d been a fine happy baby then all of a sudden after feeds she’ll cry for almost two hours straight. We’ve had zero sleep in the last few days and this momma is exhausted. I’m calling her doctor today but I doubt they’ll tell me anything other than she has to work it out. I just don’t know why all of a sudden it bothers her. Nothing in her routine has changed and she’s on the same formula she’s always been on so I don’t know how to help her. I’ve been giving her mylicon before every bottle and it tones it down but doesn’t make it go away. Picture because she’s sassy and cute.
