Help confused.!?

My baby is almost 2 months old and he's been on the same formula since birth, but 2 days ago he threw up a few times and idk why, he stopped throwing up but stopped eating normally, he usually eats 3-4 oz per feeding but he is now only wanting 1-2 oz. anyone else ever experienced this..?

Update, he's still eating hardly anything and just threw up more than what I thought a little baby could even hold, and crying like he's hurting and drooling. Still no fever...?
