The Pregnancy Discrimination Act is an amendment to Title VII which prohibits discrimination because of pregnancy, childbirth or related medical conditions. An employer is subject to this Act if it employs 15 or more people.
Whether an accommodation must be provided to a pregnant worker depends on the way the employer treats "other individuals partially incapacitated." The employer must accommodate her the same way they would someone who is not pregnant.
For example, an employee had a temporary limitation (because he broke his arm at home). The employer either changed his duties, or temporarily reassigned his duties that required the use of both his arms to someone else, or temporarily reassigned him to another job, then returned him to his regular assignment as soon as he was physically able to use both arms. Because they accommodated the employee with the broken arm, they have to accommodate the pregnant employee, or you may be found in violation of the Pregnancy Discrimination Act. See the EEOC website at the link I've included for more.
If you know that the employer accommodated other pregnant employees by putting them on the "scanner" then you should consult with a local attorney right away to find out what your rights and remedies are!

If there is really a safety concern for you or the fetus then clearly there is a lawful, legitimate business decision for denying you the job. However, this does clearly suggest consulting with an attorney. If you feel you are discriminated against you will need to comply with company guidelines for reporting it. Sounds like you are no longer employed. ANother question is whether on the post hire questionaires or other application you lied and concealed your condition when being asked if you were, about ability to perform the physical demands of this job. Consult employment counsel. You can also file a charge with the eeoc.
The hiring of a lawyer is an important decision and one you should not make just upon reading something. While I may generally provide some helpful information and an answer to your question, this is not meant to be direct legal advice to you. If you wish legal advice, many attorneys offer free consultations on certain legal issues. If you wish to be certain about how best to proceed to protect your legal interests then I encourage you to contact the lawyer with experience in the same area of law
