Would recommend actually finding out one way or another. Personally for me finding out for sure was great, it explained so many things that in heinsight should've been obvious since early childhood. Never fitting in, not knowing why I didn't, realizing eventually what it was... praying to God to make me stupid so I'd socialize better. Yeah, I was 8 years old so some immaturity was involved in that... though I wasn't entirely wrong either. In high school a lot of people actually thought I was mute, and despite high grades and amazing scores on standardized tests, even a lot of my teachers thought I was stupid... because normal people associate social glibness with intelligence... sad really.

Anyway... my point is, it can't hurt to find out for sure. It explains so much, and it's nothing to be ashamed of. It actually helps you understand yourself better, so you're better able to move ahead. Learn to laugh when you catch yourself doing "that again" and adjust as needed.

Though well, obviously, I still have other issues going on... not directly related to autism.
