2 month old inconsolable..tips

My 2 month old daughter started being inconsolable past couple days. Has to be upright and sometimes rocking. She will only sleep in her bouncer past 3 night bc she cannot sleep unless very elevated. I'm scared bc we usually follow safe sleep but her pediatrician can't see her till Thursday. Ik it's acid reflux/colic/tummy issues. Not sure how to help if maybe she needs a new formula. I tried gripe water, mylecon, Tylenol and probiotics. I even tried a different brand of bottle the only was she likes is mam. Any tips to help... I'm desperate. She will scream for a hour straight even through a bath then finally knock out swaddled in her bouncer a couple hours and start again. I'm just glad I have her owlet monitor on her so ik she's ok. She used to drink 4oz bottles every 4 hours and now she.barley drinks 1 or 2oz every 2 hours. Ik cluster feeding is a thing but mixed with the.other symptoms i just dont know if its the.formula or what. Shes on basic enfamil Also she was 4 weeks.early no nicu time
