I am interviewing with a company and just found out that I am 2 months pregnant. Should I tell the company now or wait for the offer?

HI, If there is much time for the offer to come then I think you must tell but if you think it will come any day then you can tell them once you get the offer as well. Just measure the pros and cons. Since, you are dealing with the people there, you would know better that how they are going to take the news to be. But in any case, I think it is always better to be honest with your employer. As they say, "Honesty is the best policy."
