We recommend
having the IUD taken out after you immerse because the bleeding that accompanies the removal is considered
dam makkah and does not render you
niddah. Bleeding more than two days after removal cannot automatically be considered
dam makkah, but probably will not render you niddah if you take the usual
precautions associated with staining (colored underwear, etc.).
We generally recommend
abstaining from intercourse while bleeding/staining until the bleeding subsides, even though you are not
niddah. If you follow this recommendation you are not behaving in a manner at odds with your husband's custom.
If you have the IUD taken out while you are
niddah, it may interfere with completing the
clean days in a timely manner because you need to have at minimum an acceptable
hefsek taharah, day 1
bedikah and day 7
bedikah. If you have the IUD removed before you start the clean days you would essentially have to wait until the bleeding subsides before performing a
hefsek taharah. If you have it removed during the clean days, the subsequent bleeding may prevent you from getting an acceptable
bedikah on the 7th day.
Ultimately it is your choice and you can decide when in your cycle you want to have it removed. There are no other dangers or halachic implications involved.
Please feel free to get back to us with any further questions.
B'Hatzlacha!
