I don't think background checks include medical history.  However, if the company does not offer you the job after finding out your're pregnant, then you can file a complaint for discrimination.  That's based on you having evidence of them telling you that they'll offer you the job after your background check clears. So don't worry too much. Congratulations on the pregnancy. =)

首先，象楼上的MM说的，BACKGROUND CHECK不包括这些的，主要是犯罪跟信用之类的。

况且，MM申请应该也不是这么快就能拿到跟在你的RECORD上显示的吧。美国各个机构通气没我们想象的那么快。

当然，如果公司因为你怀孕不招你，给你的理由肯定不会是这个，没人会这么傻的。
