Does a woman's waiting period (iddah) end with a miscarriage, given that she miscarried her fetus in the first few months after discovering her husband's apostasy and returning to her home country?

The woman was correct in leaving the man who apostatized from Islam or was not Muslim to begin with. The sayings of the scholars have already been detailed regarding the consequences of the husband's apostasy and the end of her waiting period from this man.
