I’m pregnant and don’t know what to do

So, I found out I’m pregnant 3 weeks ago and I haven’t found the courage to tell my mother yet as I know she’d kill me, I’m 6 weeks pregnant and only getting bigger so I don’t know what to do, I’ve thought about aborting but I don’t want to do that. I’ve tried coming up with ways of telling her but I’m at a loss, I really don’t know how to break it to her in a way that she won’t freak out so badly
