Welcome! For what it's worth, Asperger's has been removed in the DSM5, the book psychologists are trained on and use to diagnose mental illnesses. In previous revisions, autism and Asperger's were separate diagnoses for what is now "Autism Spectrum Disorder". That's the "official" part of it anyway.
What makes you worried about autism? Personally, I've found that being officially diagnosed didn't matter to me, as I am the same person regardless of diagnosis. Knowing that I am on the spectrum does help me reframe some aspects of my life through a new lens, but overall, I can't say I have any space to be worried about it, since whether if I am in fact autistic or if I just have traits of it, my experience will be the same.
