Am I wrong?

I’m 19 and 9 weeks pregnant. I still live at home (baby was a birth control fail) and my family is an absolute shit show. My dads a beyond-toxic and narcissistic alcoholic, my mom is a pushover, and my 4 siblings are amazing young adults. I told my mom last week and we planned on waiting to tell my dad and siblings (I felt my youngest sister was too young to go through a miscarriage with me, if it happens) but my mom decided it’d be better to tell him and everyone in the house earlier so that he doesn’t get mad at her (🙄🙄) I got annoyed because I REALLY didn’t want him to know right now but I let it go. I decided that afterwards, I would only tell people that I trusted.

So I felt like it would be safe to tell my grandma on my moms side of the family because I know i would want her around if something happened. My mom acted like she was on board and so I asked her today if she wanted to be there. She kind of blew me off, which upset me to begin with because I’ve been happy about it. Now she keeps asking me if I’m sure it’s such a good idea to tell her. I said yes and asked her why. Apparently she told my dad that no one else aside from the people in the house would know for now and she doesn’t want him to find out.

I’m just getting frustrated because I know I’m young and still live at home, but this is MY pregnancy and I feel I should still be able to pick who I want surrounding me right now. I don’t want this to be turned into something about them because it’s not. It’s not their pregnancy and it’s not their baby.
