I've got an interview tomorrow for a job I applied for before I found out I was pregnant. Am I obliged to tell them at the interview that I am or should I wait to see if I am offered the job? And if I am offered the job, should I tell them before I accept or wait until I have actually started? I know I won't qualify for maternity pay from them but I feel there is something morally wrong in not mentioning it...if anyone has any advice I would be very grateful.
