We've been TTC since February, so a reasonable while now. In April a job came up for the same company but on a different project which is very high profile and very exciting.. I thought then that I could not NOT go for the job just incase pregnancy never occurred and I have worked years for my career so was encouraged to carry on as normal. The recruitment period took a lonnnng time but I finally found out I got the job around mid June which was great news. Fast forward to last Monday (July 31st) and it was the first day on the new project, and also the day I found out I was 5 weeks pregnant 
Now I feel SO guilty and feel like I will disappoint them and let them down. I have 12 week scan booked for September 20-something but I really can't get my head around having to tell them I'm pregnant.
Can someone who is also/has also interrupted their career to have a baby help me come to terms with it?
