Do I have any rights if I am made to "voluntarily" terminate my position due to the fact that I am pregnant? I am not entitled to FMLA.

You may be able to file a job discrimination lawsuit. It is illegal to harass a woman because of pregnancy, childbirth, or a medical condition related to pregnancy or childbirth.  The federal Pregnancy Discrimination Act forbids discrimination based on pregnancy when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, such as leave and health insurance, and any other term or condition of employment.  According to the U.S. Equal Employment Opportunity Commission (EEOC), harassment is illegal "when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted)."   The first step is to contact an attorney or the EEOC and request an evaluation of your situation for possible discrimination.  There are time limits which you need to be aware of if you want to preserve your right to sue.  You can learn about your rights at http://www.eeoc.gov/laws/index.cfm. You can also have a preliminary evaluation by the EEOC online. https://egov.eeoc.gov/eas/.
