congratulations on your pregnancy!

i don't mean to be the voice of pessimism here, but you need to consider how you'd feel if you told them, didn't get the job (or were given a six-month contract) but things didnt' work out with the pregnancy. my own experience has taught me that it's sometimes better to withhold this kind of info. on the other hand, i completely understand why you'd feel it's not right not to tell. it's a difficult one. i think maybe go with whatever feels 'right' to you. Good luck and best wishes for a H&H pregnancy!
