Does anyone have an advice on my situation?

I hope no one judge this post, it's my first time, and I honestly need advices or just tips. I had sex with my boyfriend yesterday, it was both our first time. there was no ejaculation that happened (he never ejaculated before in his life), but there was no condom either. I was overthinking of getting pregnant because a lot of videos I came across said that you can get pregnant even without ejaculation. I'm not emotionally ready, and I am a big spender of my money(buying food 24/7, has a lot of luxury items, etc.), he has a job, and can financially support himself and others it he wanted to, but If I get pregnant I also want to be financially stable, I don't want to just live off his money because I was taught to be independent. But my most concern is, is it true that you can get pregnant? How high is the risk? Any advice, tips, or just thoughts in my situation?
