You have a good claim of at least a circumstantial case that you are being discriminated against based upon your pregnancy. Your case gets even better if the excuse they are using, the horse stable/second business, has been in existence for at least the previous years when you have been called back to work, since this would show that it was not a problem in past years and thus it is likely a pretense for discrimination based upon your pregnancy. To file such a complaint, which you should do, you need to make your complaint to the state commission on human/civil rights and the EEOC, since they need to investigate before you go to court. If you can show that your second business has never been questioned prior to your pregnancy and you can show that there have been no real performance issues, then you have a strong claim to show that this excuse is just the employer's pretext for discrimination and the EEOC would grant a right to sue letter for you to go to court after the employer.
