So family and friends know I'm pregnant but I haven't officially posted anything on my Instagram or Facebook announcing that I am or that I'm expecting . I just don't feel like it's everyone's business , I only post about it on here of course . Also I have some family on my mothers side who I just completely do not like and I don't want my baby to have anything to do with them & I don't even want them to know what my baby looks like or when baby is born or just ANYTHING
