Cows milk allergy?! POOP PIC, FTM

My boy is 3weeks and is on Similac advance. He's such a content baby unless he's passing gas or pooping he seems like he just really hates passing gas and cries so much. He seems more uncomfortable recently now. His poop always seems weird to me but I'm a FTM so I'm not too sure how it's suppose to look. Here are some pictures of his poop this morning. Do you think he may have a cows milk allergy?
