We are sorry to hear of what must be a frustrating situation.

The five day wait is mandatory when husband and wife were permitted to each other at the time she became niddah, even if they did not actually have relations. Thus, in your case, you do have to wait the five days followed by seven clean days. Day one of the five days is Sunday, the day on which you became niddah.

In the future, we encourage you to wear colored undergarments while tehorah in order to avoid becoming niddah from stains.
