Inconsolable crying

My baby girl is 8 weeks old and this week has started having fits of inconsolable crying. My husband and I do everything, and I mean EVERYTHING, we can think of to soothe her: making sure she’s full, clean diaper, gas drops, gripe water, warm bath, swinging in baby swing, walking her, holding her in different positions, singing/playing music, etc. etc.

At this point I’m honestly convinced it’s colic. I know babies cry and it’s difficult to not get frustrated... but what can we do?? Any tips or ideas are appreciated!
