Has anyone used Mother's Select Lactation Supplement with Fenugreek Plus Blessed Thistle, Fennel Seed, Marshmallow Root and their infant have blood in their stool?

My daughter is currently 5 weeks old and exclusively breast fed.

I started taking this supplement Wednesday night. The next day my baby had several loose stools and woke up Thursday morning with blood in her poop. She didn’t have any other bloody stools until this morning and has had a little bit of blood in her stools since. They have also changed from yellow mustard to more of a green color.

We were seen by our doctor today and had an X-ray to rule out NEC since she was born premature and has some underlying heart issues.

They diagnosed her with a possible cow’s milk protein allergy, but I want to rule out the possibility that the bloody stools could be from the supplements. My lactation consultant said that the fenungreek could cause green diarrhea.

Anyone had anything similar happen to them?
