Bismihi ta'ala

The question you are asking is not very clear.

Are you saying 4 months of 'iddah of divorce, after her husband had officially divorced her?

If this was the case, her 'iddah is 3 menstrual cycles.

Or are you saying she was away from her husband, and Islamic divorce was not officially conducted, but due to her absence from him, you considered her to be divorced by default and the 4 months as an 'iddah. 

If this is the case, she is not divorced, and she had no 'iddah, and your mut'ah with her was invalid, and you are not allowed to ever be with her. 

What you should do is avoid any relationship with her until you can verify the information and the circumstances, and then act accordingly, in shaa Allah. 

And Allah knows best.
