I am in my 6th week of pregnancy, I am sooo tired and feel so sick 24/7. I'm already starting to show due to being so bloated! I need to tell work but my HR department and all of my boss' are men, how to I make it comfortable to break the news to them?? And I work for an engineering company and am placed on different projects for different time periods, when should I tell them so that I am not put on a crucial project and have to miss work or once I have the baby??
