Can I get some advice ?

I live with my grandma and she will be pretty mad that I am pregnant . Me and my boyfriend are planning on getting a place together as soon as we can save the money (a few months it will take between both our pay checks .) and I want to tell them so I can have some support , but I don't want my grandma to kick me out ./: 
I'm scared . I want to tell my grandmas , my dad and mom tomorrow at dinner .
Any advice ?
