Colicky baby

Marybeth
My babygirl is 2 weeks and 5 days old. The last two nights she has screamed all night. Usually she was sleeping for almost all day and most of the night. Nothing I do soothes her. She also has gas a lot and acts like she has trouble pooping but her poop is not pebble like or hard. What can I do to make my baby girl feel better? Desperate for sleep.
