Green poop with constipation

Hi mommas and mommas to be! I am on my 8th weeks now and i just noticed I don’t poop as much as before. Like now, i usually poop 2-3 days after, i wonder if it’s normal? Also, my poop’s color lately is green as in like a vegetable green. I wonder if this is normal or do i have to worry about anything? Thanks in advance.
