Hi Bloubelle
Firstly congratulations! Such an exciting time!
When I fell pregnant I too was nervous as my ex- boss could be such a nasty person - I have thankfully changed jobs. The first thing she told me when I started my job was that the secretary had on purpose fallen pregnant when she did so that her maternity leave would end as the school holidays start ( I was working for an after-school enrichment programme which meant that when school was closed, we closed). When I fell pregnant, it was a hell of a lot sooner than we had planned. MY baby was due January 26. I was very worried about what my boss would say as I would basically just finish the long December holiday before my three month maternity leave would start which means I would not work for 4 months. When I told my boss, she pretended to be fine with it but I knew her better than that. I knew she would think that I had strategically planned all of this out. She made me work throughout December for trivial things and baby ended up arriving one month early ( 27.12.2013). Of course, she would not believe me that my baby was early but that I either lied about the due date or the doctors got it wrong.....anyways

It sounds as though you have a pretty good rapport with your colleagues and chances are that they would be very supportive. I would just ask to speak to my boss in private and tell him you have some exciting news and that you are pregnant. That is how I did it, even though I knew my boss wouldn't be thrilled. Seeing that you are the only female, take along a six pack of beer to celebrate afterwards
