Is 81 a high resting heart rate?

I've been wearing a Fitbit and just took notice of the resting heart rate. Mine is around 81. Some days it has been lower, 78, 79. But is this high? My blood pressure has always been Normal range and I've had nothing but normal Doctor checkups. We've been TTC for 2 years, both me and hubs have had every test you can think of and everything is normal. I am about 40 pounds over weight so I am working on that. Could this resting heart rate be bad?
