Kinda dont want to tell my family..

so I'm 6w1d and I really don't want to tell them, my mom never really likes kids and I'm not close to my sister's at all. I know my husband will only tell his father cause he hates his mom and his brother. I don't want my kid to miss his other family but there all full of drama. i was just gonna announce it on Facebook and if they happen to see it and don't say anything to me then I know the feeling is mutual.
