@Shaely i ate fruity pebbles this morning
That will do it, or anything similar. Anything with a lot of blue or green coloring will give you green poops. Green isn't normally a concerning color, and is often influenced by diet.
I had this for a few days. I think I read pregnancy hormones could cause it food moves quicker sometimes being pregnant. It went away pretty fast for me. No real cause for concern.
Have you eaten anything like asparagus or dye heavy foods such as fruity pebbles?
