Narrative:

I was flying to get a transponder check at ryy. En-route I flew over dobbins airspace; and contacted their controller before entering their airspace. Since my route would take me directly from dobbins airspace to cobb county's airspace; I asked the controller if she would hand me off; or if I would need to contact [them] before entry. The controller asked me to stand by; and notify me to change frequency as I was about to enter the airspace. I change the frequency shortly before entering the airspace; but the frequency was busy; and I was not sure if the controller had handed me off or not. The frequency was quite busy; and there was not an opening to speak with ATC until I was already in the airspace; at which point it was clear that my aircraft was disrupting the planned traffic.
