I told my boss at 13.5 weeks. I told HR first to make sure I knew all the policies etc but that was the same day. I just sent my boss an email asking to have a catch up and when she called me in I said I just wanted to let you know that I am pregnant. She was quite good about it. I hadn't told anyone else as I know how short our grapevine can be. I decided to tell at that point as I was feeling pretty shocking still with morning sickness and was ready to tell my friends at work.

Good luck. You'll be fine, I think we all worry about them overlooking us etc and I haven't had too much of a problem with that so far, if anything I have been working with them to get the handover ready.
