Question: My coolant is low again and I just filled it and not my heater is not working what could it be?

My coolant light came on, which has never happened before, and I added coolant. I did not notice any leaks. A day later it's low again, and now my heater is not working. Car seems to run a little rough. It has 228,000 miles on it, I have had it since it's brand new, it always has run great.
