Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Yes this is serious, your losing oil which can ruin an engine. The flashing CEL light means there is a misfire occurring from either low oil or from oil getting into connectors at the computer, coils, or injectors. I recomment check the oil cap, dipstick, and the PCV hoses off of the valve covers to the intake to see if any are loose or off. Check and adjust the oil level and drive it to the dealer if not far or call road side assitance to have it towed for free.
