Some failures in the linearization of the solution

I have a simple question for you:
In the first iteration of few timesteps of my transient simulation, the solver fails to linearize the solution (Got some 'F' for the momentum equations) but after the second iteration it does fine ('OK').
Is the first iteration of a timestep has any impact on the result written for the current timestep? Can I still trust the result of those specific timesteps?

It is the final convergence which is important. So if comes good by the end of the time step then you are OK.
