I left the bedikah cloth that I used for my hefsek taharah on my bathroom counter and some water splashed onto it. The stain on it was very small, and reddish–brown. Now that the cloth has dried, the stain is just barely visible. I’m concerned that the water that splashed on the cloth may have washed away some of the stain. Can I still show the cloth to a rabbi, or should I start counting my clean days from the next day’s bedikah?
