B’sha’ah tovah!
Based on your doctor’s assessment that you were not bleeding from the uterus, and that the bleeding is likely coming from a
wound, you were not rendered
niddah.
Going forward, you may take precautions against becoming
niddah from any further staining by wearing
colored underwear or
disposable pantyliners , and
waiting at least a few seconds (ideally 15 seconds) after urinating before wiping.
Please feel free to get back to us with any further questions.
B’hatzlacha!
This response has been updated to reflect the rulings of our current Rabbinic Supervisor, Rav Kenneth Auman, regarding waiting before wiping.
