I'd ask him honestly & say straight out that there seems to be a number of persons calling regarding interviews for the Receptionist position, of which you (he) offered yourself.

Does this mean since informing you (he) of your pregnancy that he no longer is offering/considering you for the role?

That way it's all up front..

He may say "When you told me you were pregnant I assumed you were telling me you didnt wnat the role, or he may say, well I really need a permanent person & if you are pregnant & in turn going to be taking time off then I dont think the role is yours (Or some such thing!)"

But ask him, after all what do you have to lose???? Good Luck!!

Hmmm, interesting that so many are calling to cancel their interviews!????
