Tummy Troubles

So my baby, not even a week old, is breast fed. She gets fed on her cue. For the last day she’s been eating like crazy (cluster feeding maybe?) And pooping but it’s like diarrhea and we can hear it from across the room. It sounds like bad gas but it’s poop. We can also get her tummy rumbling throughout the day. Has anybody else experienced this?? I’m not sure if this of normal or I need to call her pediatrician.
