Last time I didn't tell anyone in my family that I was pregnant until 17 weeks (I was going to see them at 19 weeks and thought it would be awesome to shock them with my big belly but DH accidentally mentioned it to my mum beforehand). I also have a friend who never mentions she is pregnant until her belly is too big to deny it, and I don't think she is rude, just private. It is your own decision, lease don't feel under any obligation to tell people before you are ready.
