how do you tell your mom you’re pregnant and getting an abortion?

i’m 26, first time being pregnant, and i don’t feel like it’s a good time to have a baby! i don’t feel like i have my shit together at all. I want to tell my mom, but I don’t know her stance on abortion at all. and I’m scared to tell her I’m scared of what she’ll say and I’m scared of what she’ll think of me. Is it better if I just don’t tell her? I just want some motherly support.
