Hey fellow nutmegger.
You should be fine. Be careful with over heating. Fermentation temperature is a huge factor in how your beer tastes. When you have high yeast activity in the first week of fermentation, the actual temp of your beer can be 4-7 degrees higher than the ambient temperature.
I'm sure Revvy will pop in here and let you know about how lack of airlock activity doesn't necessarily mean lack of fermentation.
Relax, don't worry, have a craft brew.
