I know how you feel Tamara... I didn't tell most people at work until I was about 5 months along, and once I did I immediately got told off for carrying and lifting, and generally just doing things that I'd been doing all along. Although I kept doing most of them anyway (I figure I'm pregnant, not injured, and I know whether my body can handle what I want to do!). The main problem for me was that my memory practically disappeared - I kept forgetting what I needed to do next, and had trouble remembering if I'd done something I'd intended to (I have a desk job BTW). But my last day was yesterday, so now my brain can turn into mush without it being too much of a problem
