How to handle my mom?

I just told my mom I was pregnant with my 3rd child.. She doesn't support me in anyways emotionally, or financially I have lived with my fiancé for 4 years, anyways she was basically like cussing me out saying I'm not responsible, and that I need my tubes tied and this and that for no reason, even spelling my daughters name wrong. (Might I add she has nothing to do with her grandchildren, then when I point it out she has the never but I love my grandchildren) yeah right anyways, I called her a shitty mom mad and even shitter grandmother. My son wanted her to see him for over a week we called her every day and he asked her multiple times to come see him and she never would. I'm just idk, maybe cause I'm pregnant I'm just emotional, but idk. It's not like my mom was ever there for me. Am I wrong to feel mad...
