Grr work annoyances

So I am 39+3 and due on Sunday. My boss is out of town this week traveling but comes back tomorrow. I had already decided I was going to work remote the rest of this week since she was out; typically not an issue since I'm a director and not something we usually have to ask to do. So I emailed her that and she is all bent out of shape. And I am definitely not planning to be working in the office after my due date at all. That is dumb because I could go at any time. Esp considering I was 3.5 cm on Mon! Seriously, come on...give me a break, I am not superwoman....
