My 2 month old woke up screaming

Lizzi
My 2 month old woke up around 4:25am screaming bloody murder. She did wake up around 3am to eat. She ate her normal 4 to 5 oz. Burped very well. Now she's just crying and screaming and don't stop. I have given her some gas drops to see if that would help. She's never done this before and neither has my oldest.
