Is this normal newborn formula fed poop?

Brianna

My daughter is 3 weeks old and we recently switch to formula full time. My first daughter I breastfed so her poop didn’t look this way. What concerns me is how runny it is. She doesn’t have a fever and has plenty of wet diapers. She did vomit/spit up this morning but was fine for most of the day. Only recently got a little fussy. Is this normal or diarrhea?
