5 month old poop

My daughter will be 5 months on Monday. Anyways, she normally doesn’t poop everyday, maybe once or twice within a weeks span.. She is breastfed.. Anyways, she’s been pooping almost once or twice everyday & today I noticed her poop looks alittle green, picture down below.. it’s normally a yellowish/orangish color.. is this normal? She’s been fussy today, but I thought maybe it was because I noticed she has a tooth coming in & she isn’t sleeping well.. but now I’m thinking maybe she has a belly ache? What do you all think?

EDIT: I forgot to add She has started baby food (told to do so by doctor) the last time she had some baby food was about two days ago & her poop was normal color until today.
