Is there a difference between ADHD and ADD?

Within the past few years friends/family have teased me about "getting checked out for ADD".Yes,it's jokingly,but after a while you wonder.I've taken several online "questionaires" regarding ADD and each one said strong liklihood of ADD but no hyperactivity.I went to my doctor to talk about this and throughout the whole conversation he kept saying ADHD as if there were no difference between the 2.He said I would have had problems with hyperactivity as a child.Based on my research this isn't true with ADD.I've had these miserable symptoms for about 6 or 7 years now,but some of them for as far back as I can remember.Can't sit through tv shows but can watch a movie with no commercials,severe procrastination,never finish any tasks,bounce from one project or activity to another before finishing it,impulsive, etc. It's frustrating because about a year ago I started my own business after being a 10 year stay at home mom. It's affecting my work and I'd really like to get this under control.
