My mom has asthma, I'm showing symptoms of it. Testing tomorrow, what should I expect?

When I first started getting muscle cramps, wheezy, and short of breath, my dad took me to the doc, (fyi, when I remembered about the short-breath thing, the guy'd already said it, like, two seconds before, so it woulda seemed like I'd wanted asthma, and I stupidly didn't mention it) and he said, "Come back in a month if it doesn't get better." Which everyone in my family thought was dumb, but it's been a month. I'm scared of wasting the testers' time or something, so what should I expect?
