When a woman declares herself
niddah based on misinformation or an error, she may retract once she discovers the error and clarifies the situation.
Therefore, you may consider yourself
tehorah since you mistakenly believed you were
niddah from the spotting following the
IUD replacement. You should continue taking precautions against becoming
niddah from any further
staining by wearing colored underwear and
waiting 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.
