Constipation.

My baby (2 weeks) has been fussy the past couple of days. We thought it was gas but today he passed clay like stool. He is formula fed right now. I accidentally gave him similac pro sensitive a couple of times instead of pro advanced which is what he has been having. Could that be the reason and will constipation pass on its own?
