Probably; I would refer to your employee handbook or contact the HR department.
I am concerned that you were fired during a maternity leave; it is illegal to fire an employee because of pregnancy; if you believe this to be the case, contact the EEOC.
If you plan to find a new position, drop me a note: I do career and job search coaching and will be happy to help you with resumes, coverletters, job search strategy and interview prep.
