My girlfriend might have gotten me pregnant?

So basically me and my girlfriend have been getting intimate for like one month but only had actual sex like 2 weeks ago and i think she might have gotten me pregnant oh yeah its bc she is trans so it is possible for her to get me pregnant 😅😅sorry should have mentioned that earlier

And my issue is that if she really did get me pregnant then idk what to do bc my mom never gave the the talk regarding sex ( or even periods really just gave me a pad and went with this) and like I don’t think i can tell her that bc then I would have to tell her that my gf is trans which i am scared of bc she already wasn’t very supportive when i told her i was in a relationship with a girl idk how she will react to this, what should i do? Obviously i know not to do anything yet and to get a pregnancy test first but u know its my first pregnancy scare so i am gonna act pretty irrational 😅😅

Thank you for any help
