Bloody streaks in stool

Sorry, no help here... 8 weeks old. We had mucusy green poops and some blood in them. Only been a week since I eliminated dairy, but it seems to be better. She's still fussy/uncomfortable a lot of the time, but she's not sreaching in back-arching pain anymore. Hoping that it'll get even better as her gut heals, and then we can know for sure that it's the milk protein allergy.

But as someone who's comfort food is a glass of milk, it's really doing a number on me to cut out dairy entirely. I barely know what to eat as my entire diet had cheese on it. They said we can try to reintroduce around 4 months.
