Hi kashiic,
There is a correlation between autism and gender dysphoria, though it is not 1:1. Ultimately, most people with gender dysphoria don't have autism and most people with autism don't have gender dysphoria, despite a pretty significant relationship. If you are really concerned it may be worth talking about it to your GP a bit further. There is a lot of research coming out about gender dysphoria and autism, so know that if you are having these concerns you are not alone.
The main characteristics of autism are difficulties in social communication and interaction, plus restricted, repetitive patterns of behaviour, interests and activities - and these symptoms can't be better explained by other disorders or environmental factors. I only mention this because some pop-psychology sources can disregard this and focus on some atypical or 'quirky' symptoms of autism, some which can even be generalisable to neurotypicals. Furthermore, this symptoms have to be severe enough that they cause significant distress in your life for a diagnosis to be valuable.
If you're still interesting in learning more, scientific articles can be a great resource, despite some of them being wordy and convoluted. If you can find it online, there's one entitled "Mentalising Moderates the Link between Autism Traits and Current Gender Dysphoric Features in Primarily Non-autistic, Cisgender Individuals" by Kallitsounaki & Williams (2020). It found that autism traits was correlated with gender dysphoric traits, and builds on that finding with mentalising as a contributing factor. Remember that these correlations aren't perfectly strong, so if you feel like any of these findings don't represent you, they probably don't!
