Announcing my 2nds birth?

When I was pregnant with my first i told everyone the gender, name & when I delivered & first pics. With this pregnancy I've been stressed. I feel like my little family has absolutely no privacy. There is only suppose to be me, my son, my boyfriend & our unborn living in our house but I have family constantly coming over. I currently have an uncle and cousin that have stayed with me for over three months for free! It's taking a toll on my relationship. Our family is telling us how to raise our son & how to get ready for our 2nd. I'm 22 & both my parents are deceased so I feel like I have no one to talk to that would understand me. ANYWAYS is it wrong that I do not want anyone to know when I go into labour or know the name of my baby. It's good enough they know they know when I'm roughly due & gender. I just want something between me and my children's father. I think it would be difficult though due to the fact my first was due April 7, 2013 but born April 12th with two of his first cousins. I'm also due April 7th again. Needed to vent. Help. Advice?
