Family mad I didn't personally tell them about pregnancy?

Sa

So I made a post on Facebook about being pregnant. We had told my parents and brother and my husband's parents and siblings in person. I got an email from my mom saying my aunt is mad that she found out from Facebook and she called my mom complaining but didn't call me. I'm not stressing about it, we don't talk that much anymore since I live across the country. Haven't seen her in 4 years. Was I wrong for not personally telling her? Or is she blowing this out of proportion? I feel that it's MY (and hubby's) pregnancy and it's really nobody's business how we announce. Any thoughts ladies?
