We are sorry you are going through such a difficult time. Halachically, there are a number of things you could do that we hope will help you get to the mikveh.
1. If you are able to get a clean hefsek, you should minimize the number of bedikot you do during the seven clean days. You must perform a hefsek, and one bedikah on the first day and one on the seventh day of shivah neki’im, and it is a good idea to add a bedikah in the middle on the third or fourth day, at a time that you suspect you are not staining. Any problematic bedikot should be shown to a rabbi, and be sure you explain your situation in detail as you did in your email. Extenuating circumstances are an important consideration in halachic ruling.
2. If you are experiencing problems with staining on underwear as well, please let as know as there may be halachic interventions for this. Avoid looking at toilet paper at all times in order to avoid additional problems with staining.
3. Once you have gone to the mikveh, BE”H, be sure to wear only colored underwear, and as always, avoid looking at toilet paper.
4. Medically, you should ask your health care professional if you could be treated for the fibroid. You should also explain your situation to the doctor (that according to Jewish law you are forbidden from all physical contact with your husband as long as you experience uterine bleeding), and see if any additional possible cause of bleeding could be detected which may be either treatable or used as important halachic information in determining your status. You may want to refer your physician to the section of our website designed for medical professionals, Jewish Women’s Health, so he or she can better understand your concerns.
If your D&C was recent, it is possible that you are still bleeding from the procedure. If you would like to get back to us with more details, there may be additional help we could offer.
