My husband and I found out we were pregnant on may 3 (total surprise) we have 3 healthy children 16, 12,6 (one miscarriage). I thought we were done but obviously the universe had bigger plans for us! We are both excited and have only told our moms and my best friend who lives far away. I'm currently 6+1 and the baby is due on my 38th birthday! My first appointment is next Friday. We are waiting until at least after that (if not until 10 weeks) to tell our kids and then I know it'll spread like wildfire. 
How did you ladies announce your 4th (or more) pregnancies? I feel when your family is bigger it gets tougher. I guess I'm also anticipating some negative remarks.
