Fussy Night Time Baby

Hello! I’m a little worried about my little one. She wakes up and cries from about 8:30Pm- 11:40pm each night. I feed her, change her, hold her, rock her, swaddle her, everything I could think of and she still cries. Could this be colic or something else? We have an appointment on Tuesday but I was just wondering if anyone had experience with this and had success with soothing their little one.
