My opinion on the matter is that one should always try talking to a professional if they suspect they have ADHD. Our understanding of it is limited, but in my experience at least, getting to try meds is what cemented it; the fact that amphetamine slows me down, directs my thoughts, and lets me focus on what I want to do is a world of difference from the experience of average neurotypical person taking amphetamine.

And even if you don't have it, and/or meds aren't for you, then even so, just from the fact you think you might have it implies to me that you feel you have some symptoms/traits in common, and so you might benefit from learning some of the coping strategies ADHD people develop to deal with those symptopms/traits.

It's always better to try and know everything you can and open every option available to you, imo.
