Breast fed Baby Diarrhea?

Any clue what that looks like?? My daughter is the first kid I have been able to breast-feed so this poop situations all new. 

Can breast-fed babies poop be watery without any mustard seed like stuff in it? Because that’s what the last few of hers have been yesterday and today. Plus she has been very fussy and gassy and just a little bit off. Not sure if it’s just today or if she might be possibly coming down with something. If she still acting off I’m gonna take her to the pediatrician tomorrow.  The acting strange just started this evening.  no fever or anything that I can see and her soft spot looks good. She six weeks.
