Green poop

B

I’m not sure if this is even the right place to look/ask for input but here I am. My child is 3 and for the past month or so, not every time but often?, there’s been struggles when pooping. It’s as if my kid is constipated or something. She whines when pushing and it’s usually just like a small poop and lately been green or dark brown. Sorry if it’s TMI, I’m just wondering if I should make an appointment, I don’t want to unless it’s an emergency because of the “situation”. Constipation doesn’t seem like an emergency, if that’s what it is. Idk, any answers are appreciated
