Food upsetting baby


so I've been breast feeding since she was born she is now 2mths. I've eaten like I always have including junk foods and soda and never ever haf any issues with her. last night and tonight for the first time since she was born I had shrimp and eggs all if a sudden she started to get really gassy and getting upset and now when I offer the boob she gets upset I'm worried she won't eat thinking its going to upset her tummy and make her toot. could it be the shrimp or eggs, and how long until its out of my milk if it is the shrimp or egg
