2004 Honda Civic EX Thermometer Fluctuates

My thermometer started fluctuating the other day, when I would drive 35 or under it would red line on the "H" regardless if my heat/air was on or off. But my car is NOT overheating. I checked the coolant and it was where it needed to be. I also don't have any heat coming out if I go under 35 mph. Any suggestions on what could be going on? Is it a bad thermostat?

Yep. OP probably only looked in the plastic reservoir, not the radiator.
