Pregnant and 19 almost 20

Os last night me and my fiance found out that I am pregnant after being 12 days late for my period. I am freaking out a bit because we are planning on moving out by this summer but I am living with my mom right now and I'm not sure if anyone will hate me or accept me or if my mom will kick me out or try to kill the baby. I'm unsure what to do is there any advice for me at all? I know I am going to try and wait eight weeks before saying something.
