Sudden inconsolable crying at 8 weeks?

My son will be 8 weeks on Sunday and for the last two days he is crying almost 100% of the time he's awake. Like blood curdling cries. Won't take his pacifier, doesn't want to be held, doesn't want to be put down, doesn't want to be in the carrier, or stroller... Just unhappy no matter what. Doesn't seem like anything is wrong with him. Fed, changed, burped, no fever, not too hot, not too cold... WTF is happening, I'm losing my mind!
