I had a previous thread asking if there was any point going to a job interview at 21 weeks pregnant in which I said I'd tell them at the end of the interview that I was pregnant. The interview went terribly so I didn't tell them but I was offered it over the phone today and I accepted. I was in shock but I still didn't tell them. My contract begins 1st March and I'm due in May. 6 months probation. My question is how do I tell them now that I am pregnant and can they withdraw the offer (under a different reason of course) as I've no official contract yet? I imagine they'll be annoyed as I wasn't straightforward and I have no idea how to go about it now.
