Need advice

I’m 17 and I had a one night stand two weeks ago with my best friend and we both agreed after that we’re better of friends and we should forget it happened. Today I found that I’m pregnant and idk what to do. He still lives with his parents and I do too. I’m quite anti abortion so that’s not an option because I can’t even think of ending my child’s life before it even began. I don’t think I’m mature enough to raise a child and if I tell my parents they will definitely kick me out, they have always told me to wait for marriage and I’m quite scared to tell them. If anyone has advise please help . Help
