Can I be fired (without notification) while on maternity leave?

I had my son 8/24/12, I was not due until 9/15/12. I had sent in all required FMLA paperwork, even had my Mother fax it to ensure it was there a monthy ahead of due date. While I was off I recieve a letter from my companies FMLA Coordinator that I did not qualify for FMLA, as I was about 50hrs short of the 1,250 hours mark. It went on to inform me that I could only take three weeks off. If I took longer than three weeks my position would be terminated, however if I came back within 90 days I would keep my current seniority. This letter was written the last day of the third week, and I recieved it in the middle of my fourth week off. I tried calling FMLA Coordinator multiple times, leaving voicemail each time, and never got a response. I then called the DM who informed me I could reapply for my job, but it was at their discretion if I was re-hired. I applied, and of course was not re-hired. So I then filed for Unemployment Compensation. The company first claimed that as of 8/19/12 I was medically unable to perform my duties, however I worked 8/19/12, 8/21/12, and 8/22/12. I was off on 8/23/12 and had my child 8/24/12. They then claimed that I was discharged on 8/22/12, no reason for termination was given and I was never notified that I was terminated. I also visited my place of employment the first week in September and my Manager told me how he couldn't wait for me to come bac from leave. Why if I had been terminated would he be telling me this? Lastly, they claimed that I quit on 9/20/12 for personal reasons. This too was false, I never quit my job and furthermore I never spoke to anyone at my place of employment on that day. Every reason they gave was false! I was also advised by a friend that I was legally allowed six weeks in Ohio, even if not covered by FMLA, therefore they violated law by telling me I could only take three. It irritates me the most that two other employees took six weeks off for their maternity, neither had been there a year or had 1,250hrs. Yet they came back to work with no issues. I think I was really let go for complaining about major issues such as retaliatory write-ups and members of management discussing my medical issues with other employees. I was just wondering if I have a wrongful termination case and what I should do.
