TMI baby poo green

Sara • IVF pregnancy Mama to baby girl 11/2/19

LO is 13 weeks old, EBF... Usually her poo is a slimy orangy color, sometimes a mustardy seedy, but once last weekend and again today she's had a poo that looks like this... Kind of mucousy, green... Has anyone experienced something like this? Normal or no? We've already had her tested for allergies because of eczema, she is not allergic to milk, eggs, peanuts or oats. She's acting normally, no fever, not any more fussy than usual.
