Advice pls

I’m 22 years old and found out I’m pregnant I got fired from my job because I was stressing but I found a new job which I start tomorrow. I didn’t tell my mom I’m pregnant yet because I’m scared I feel like she is going to disown me or get really mad at me. I do not know wat to do. I feel like when I tell her she is going to say she is disappointed in me and I just got back working again and that I should be doing this and that instead of being a mom
