If it is not a leak, coolant can be lost due to a blown head gasket or cracked block or head. I doubt it is one of these issues though. It is likely a leak and you just have not found it yet. I think you are safe using non-Nissan coolant for a few days, but I would flush it all out and replace it with OEM once you fix the problem.
