Gassy baby.. advice please!

My poor baby girl screams almost every time she passes gas. What can I do to help my girl? I've tried gas drops and Gripe water. It does help sometimes but not always. She has a GI appointment on Monday so maybe we will get some answers but I am so nervous. What will they find/will it be bad/did I do something during my pregnancy that caused this...etc. my Postpartum depression and anxiety has been at an all time high lately. My fiance seem to always snap and argue at each other when she's screaming. I don't know how to add a video but here's the link to the video that's only visible to those who click on the link. It is an im in pain scream right? FYI I only recorded the video to show the pediatrician/GI specialist. https://youtu.be/a0Ys6Q95r2A
