Saying an ambiguous word of talaaq while arguing

Q: I understand that there has to be a niyyah when one says a phrase of kinaya talaaq. I wondered that if one is arguing, and one gets a feeling like wanting to divorce or a feeling like "come on do it now (leave her) and then says a kinaya statement like "go to your father", all happening in seconds, is that a clear intention that is necessarry? But if the person asks himself a few moments later did you want to definetly divorce her now by that, the answer is no. What do i do now as i dont know whether it was an intention that counted or not?
