Green poo poo

My daughter is 7 weeks old and I am breast feeding her.

Her poop has been yellow and seedy now I'm starting to notice its turning green, sticky and hard to wipe off her bottom. I wanna know if this is normal.

Is it because of me? About what i ate? What should i do? Im so worried and curious if this is normal for a 7 week old baby who is strictly on breast milk. Thanks!!!
