HSG during shivah neki’im

9 May, 2005


My husband and I have been trying to conceive for 9 months. I am starting to undergo fertility treatment, and my dr. wants me to have an HSG done on day 11, the 5th day of shiva nekiim (I almost always am able to go to the mikvah on day 12). I know that the dye might affect my bedikahs, is this ok? Do I need to get a heter to discount the dye? Also, the Dr. said that there may be cramping and possibly a little bit of spotting…will this affect my going to the mikvah? I am supposed to ovulate on day 13 or so, so I wouldn't want to miss this cycle.


By performing a hefsek taharah, you established a chezkat taharah (halachic presumption that you are not bleeding).  Therefore, if a brownish color turns up subsequently on a bedikah, and you know it is a dye, then it should generally not present a problem on regular bedikot.  (A dye that cannot be distinguished from blood would present more halachic difficulties on a hefsek taharah. In your case, since the hefsek taharah will be done well before the HSG, this should not be a problem.)

We suggest you do a bedikah on the fifth day before the procedure, and then avoid doing bedikot altogether until the seventh day (you must do at least one bedikah on the seventh day). Bathing on days 5 and 6 should help minimize the amount of dye still present. If there is a brownish stain on the day seven bedikah you would need to ask a halachic question – be sure the Rabbi knows that you have had the procedure, that a brownish dye was used, and that you are trying to conceive.

As far as the spotting, we can't help until we have more details about what actually happens. We hope there will not be any spotting, or that it will be a small amount which will not affect your tevilah.  You can help prevent large stains from accumulating by changing underwear frequently. Keep in mind that not all staining invalidates the clean days.  Even if you find a stain larger than a k'gris on white underwear, you should not assume the clean days are invalidated. You should ask a halachic question, mentioning the procedure, your difficulties conceiving, and the importance of not delaying mikveh this month. Please see our article on Stains for information on this topic.
