Is this normal?

Justine • First time Mother of one beautiful daughter. 👼🏽

My daughter is 11 weeks old and today was the first time I saw these solid nuggets in her diaper there was a bundle of about 6-10 of these along with her normal runny poop she was screaming in pain trying to pass these is this normal with her being so young? I’ve called her pediatrician waiting for a call back and I’m just worried being a first time mom..
