First time around I told my boss as soon as we knew and it spread like wildfire through the shopping mall I worked in. When I m/c , that news didn't spread along the same grapevine, so I got a lot of comments like "Gee, you're not showing yet" and the like, which really pushed my emotional buttons. Second time around, I swore I was saying nothing.....but two days after I found out, I got a promotion with a lot of costly training involved and my boss was talking about my long term position. I promptly burst into tears and told her. She was great, still wanted me to keep going and didn't tell anybody until I did at 14 weeks. I continued to work until three weeks before my due date, and in hindsight, it wasn't early enough.
