I work from home and only see my co-workers once every few months. I will be seeing them tomorrow, but since I am just 12 weeks and have my ultrasound on Thursday, I would feel most comfortable not announcing just yet.

My other option is to announce during a bi-weekly Skype call with my department (7 people including myself) either at 14 weeks (the day before we tell our families in person) or at 16 weeks. Of course, I would announce to my manager separately and before announcing to everyone else.

My question is, if I wait until 16 weeks is that "too late"? Will they wonder why I waited so long? I'll be the first female to announce even though my manager's wife and another co-worker's wife have both had babies.
