Is this a Triple Divorce?

You have stated that your husband had previously issued you one divorce and thereafter, after reconciling, he had issued you two divorces. Based on the information you have provided, all three divorces are valid and effective and the marriage had irretrievably terminated upon the third divorce being issued. Consequently, both of you are Haraam (unlawful) for each other and it is not permissible to reconcile even by renewing the marriage.

The Iddah* commenced after the divorce was issued.

*The Iddah for a menstruating woman is three menstrual cycles.

The Iddah for a woman in menopause/woman who does not menstruate is three months.

The Iddah for a pregnant woman is till childbirth.

NB. The above ruling pertaining to the divorce is applicable considering that the first divorce that your husband issued to you was a revocable divorce and you had reconciled within the Iddah period. Or if the Iddah period had expired, you’ll had reconciled by renewing the Nikah. The ruling may be different if the situation was different.

And Allah Knows Best
