I don’t know what to do

I am 26m and I just got out of a 3 year relationship around 4 months ago. I wasn’t really looking around or anything but a girl I used to talk to in high school with popped up on my social media and we started talking a bit. We eventually made plans for me to pick her up and go on a hike. She was very nice and quiet I just assumed she was shy but I had a good time with her. After talking for another week or so we decided we would go camping for the weekend as it was something we both loved to do. The camping trip went great. We did have unprotected sex (I forgot to bring condoms) and it was the heat of the moment thing but she assured me she was on birth control. This is where things get interesting. Everything was going great until it wasn’t. I dropped her back off at her apartment and I offered to help her take her stuff inside now this was the first time I’d been in her apartment and upon walking in it was very cluttered and disorganized and had multiple unclean cat boxes everywhere. This was a pretty big turn off to me but she told me she was in the process of moving so that’s why there was stuff everywhere. I helped her bring her stuff inside and went home. Fast forward a couple days later and I went back over there to spend some time with her. We didn’t go to bed until around 2am but she has four cats who are very very active at night and will come on the bed and bite at your feet and keep you up. I was a little bit frustrated by this and decided I was going to leave around 6:30 and politely explained to her that I needed to leave because I was unable to sleep in that environment. This is where things went south. She started yelling at me and chased me out of her apartment demanding I come back to bed. She also claimed I had left stuff in her apartment that I needed to grab (which I knew wasn’t true) and tried to persuade me to come back in. I was a bit concerned by this so I insisted that I was going home. I have not seen her in person since and it has only gotten worse. She constantly texts me upset with what I’m doing and how I haven’t came and seen her which it’s only been a few days. She calls me names and gets really nasty over text. She now is claiming she’s pregnant and she took a test but the one line was to “faint” for a phone camera to pick up. It’s only been 8 days since we had sex and she’s also claiming she can feel that she’s pregnant and that she’s sick and doesn’t feel good. She has already made threats that she will never let me see the kid and never talk to me again all because I didn’t come see her this weekend. On top of that she also sent me a picture of her with an alcoholic beverage and told me it’s ok to have a drink this early on in the pregnancy which is insane. I also found out that she has a minimum wage job, no vehicle and after the condition of her apartment and the way she tries manipulates me and talks nasty to me I really want nothing to do with her. I’ve always wanted kids and do not want my kid to grow up without a father. I have no proof that she is pregnant but she has text me about being pregnant non stop for the last three days but has shown me no proof. I have been really stressing out and don’t know what to do.
