Saying I'm preg

Ok so I invited my in laws out for breakfast to tell them I'm preg but when it got there they invited my husband sister and her husband and  my aunt in law.  Ok so before we get to the table I noticed that my sister in law pulled her mom aside then pulled her dad aside and told them she was preg.  So my breakfast to tell them I was preg became her breakfast that she is preg.  Me being me I think everyone needs their time to shine when something amazing is happening. So my question is when do I tell them I'm preg without raining on her shine?

When and HOW did you tell them? Sorry she rained on your parade!
