I need suggestions please

So I found out I'm pregnant. I still live with my mom and I'm worried that she is going to kick me out due to me being pregnant. I'm still with the guy that got me pregnant and love him to death. Yes I know I'm 25 and suppose to be on my feet. And living on my own. But I hated to buy my own place then marry someone and then sale it. I mean I am planning on getting married to him soon anyway and moving. But I'm still really worried should I just try to move out sooner?
