Now when I say potential, i'm actually talking about a .1% chance of this happening, but my lizard brain keeps going off with worry lol. FYI, I did "wrap my willie" before anyone asks

I met this girl who lives near me, we don't really know each other apart from a first name basis. We decided to hook up, everything went smooth, but I still get this feeling in my head. She's had a bunch of boyfriends and play partners (I test myself) over the months and I was one in the crowd, but what's the chance that she could possibly single me out if she has the child somehow?

Now on to the legal part. If she decides to pursue it, what's the chance I can avoid this altogether and explain to a judge what happened? I took all the proper precautions, and to be honest we are still strangers to each other and suddenly becoming parents would be hella weird. I also have a special needs sibling i've been taking care of for..12 years now?

I don't mean to sound like some selfish prick throwing away accountability, but I have heard the horror stories. My state requires me to pay 25% not including medical and stuff, and that would turn my life upside down completely. What's the best case scenario to fight this, in case I get a knock on my door 9 months later?
