No but it might be the end of the begining. Just could not help it. Too obvious to miss. First do or have a pressure check done on your cooling system to see if any indications of a leak are there. That water pump for example may not seep with no pressure. After driving the car someday after it is good and warm park it and watch the ground for a drip with the engine running might help to locate a possible leak as well. I would not jump to any conclusions at this point with as little information and evidence as you have at this point.
