Spilling the beans!

My husband and I have been TTC baby #1 for about six months now.  I was wondering how long everyone else waited to tell friends, family, co-workers, post about it on social media that they were expecting?!? I know I will tell my husband right away and then we will tell our families. They all know we are TTC. I have a few close co-workers too I would want to tell, but what about everyone else? The reason I'm asking is because I'm seeing it more where people post about it right away on FB. I have two friends who are pregnant right now and they announced their pregnancies at about 6 weeks on FB. Another friend waited until she was 14 weeks. I know they say it's safe to wait until you're about 12 weeks or so.  When did you announce your pregnancy on social media?
