What must a traveling woman do who has been combining and shortening prayers for two months, believing it permissible due to her instability, and then it becomes clear to her that her action was incorrect?

Scholars have differed regarding combining and shortening prayers for a traveler residing for more than four days. However, not combining and performing each prayer at its appointed time is better if there is no necessity. Likewise, completing the four-rak'ah prayer is better for a traveler residing for more than four days, to avoid scholarly disagreement. As for what occurred in terms of combining and shortening prayers based on a previous understanding or the opinion of some scholars, there is no sin in it and it does not need to be repeated.
