How long of nonpayment to be evicted in Florida?

I could have sworn I read somewhere that you had to be 2 or more months behind on your rent before a landlord can even think of starting the eviction process, has that changed? Or did I read it wrong?! Please clarify. I am 11 days late & shes already threatening, I dont have any reason not to pay but hubby & I just lost our jobs, & are waiting to get some money, but she wont budge.
