First, regarding your eligibility for FMLA: if you have been with the company for 12 months (including temp time) and you have worked 1250 hours, you are eligible for 12 weeks of FMLA. If you've already used some FMLA time, you need to be careful about counting your weeks of eligibility.
Regarding unemployment, if the company denies your request for additional leave and you are terminated, you will be eligible for unemployment once you are released to return to work by your doctor. In Ohio, if you are "ready, willing, and able to work" and you are terminated "through no fault of your own" then you are eligible for unemployment. The Ohio Department of Job and Family Services administers unemployment. They will want to see your doctor's release.
Finally, you should explore a pregnancy discrimination claim against your employer. From the facts in your question, I can't tell if it applies here, but it's worth considering.
