I had 2 sisters visiting from overseas at 5 weeks, and one of them guessed because I wasn't drinking wine, and wine is like a family ritual at dinner so I didn't deny it but I promptly told my immediate family right away. Actually, I was going to tell them because it was a rare opportunity to have my sisters here with me. It was good I told them because they wanted to go on a big hike and I didn't want to over exert myself.

I am now waiting until after the nuchal scan to tell friends. I think one of my couple friends has guessed (again with the no alcohol drinking) but they're respecting my decision to wait to announce it. I don't think anyone else knows, but I work standing up most of the day and sometimes I want to tell the people I work with so they'll give me some sympathy and be nice to me
