Had s&x with a homeless woman and she’s pregnant now

A few months ago we met at the gas station. She didn’t have any money on her and she was trying to get to a bus stop a few blocks away. I drove her on the way we were chatting about everything. We really got along and after finding out she didn’t have anywhere to go I asked her if she’d like me to get her something to eat. But I just wanted an excuse to keep talking to her because we had so many things in common and I enjoyed our conversation. Her story and how badly things have gone for her personal life ever since the pandemic. At one point I remember her asking if this is okay (she was about to kiss me). I told her it was more than fine and we kissed. One thing led to another and we had sex in my car.

We saw each other a few more times at coffee shops to talk over the next weeks until she told me she found a job an hour away and it was also close to a shelter until she could afford her own place to live. That’s a little bit of our background story so you see how it got to this. First time in months she contacts me that she’s over 4 months pregnant with our baby. It caught her by surprise and she says she was so stressed with work it didn’t really hit her until she remembered we had sex.

I’m a little overwhelmed ( I have proof the baby is mine). She said she understands if I don’t want to be involved with the way it all happened. I don’t feel that way at all. It’s scary but once I actually saw the ultrasound photo of our baby my heart fluttered.
