Thinking about getting a diagnosis

Hi, I'm new here and am looking for some advice.

I have an existing diagnosis of Dyspraxia, which I think is correct for me, but lately I've been wandering if I could have Autism as well.

The complicating part for me is that I was assessed as a child, but I was viewed to not meet the criteria. I know women are less likely to get diagnosed due to masking (I think I perhaps do that), and my assessment was 20ish years ago, so it is a while ago.

Does anyone have similar experiences of not getting diagnosed on the first assessment, but later getting one? Is there any benefit of getting a diagnosis, given my existing dyspraxia diagnosis? I know it is possible to have both, so I'm not disputing the diagnosis I have, I'm just wandering if I could have both and if it is worth pursuing.
