Sorry to say, but that is a classic sign of a blown head gasket. When a leak develops in the head gasket it can cause one or many different problems incluing: it may allow engine oil into your coolant. It may also allow coolant into your crankcase oil. Or it can allow coolant into your exhaust system (appears as white exhaust smoke and smells sweet like coolant). You say your checked your oil level and it looked low. That is because your oil is being drawn into the cooling system. You should only drive this car in to get the head gasket replaced. Do not keep driving it until you get it fixed or you could cause much more damage.
