CVS during shivah neki’im

24 March, 2019


I am currently 12 weeks pregnant. Last week I had heavy bleeding which made me a niddah. I will be having a CVS (chorionic villi sampling) during my Shiva Neki’im (Day 3) and I am concerned that it may cause staining. In this case would it be permitted to wear colored underwear following the procedure and skip bedikahs for a few days?


B’sha’ah tovah! We are sorry to hear of the bleeding you experienced.

We recommend performing a bedikah in the morning before undergoing the procedure. You may then omit bedikot until day 7. If you are still staining by day 7, you may delay your final bedikah (and thus mikveh immersion) until day 9 at the latest, assuming you performed a bedikah on day 3. (As a general rule, no more than five days may elapse without a bedikah during the shivah neki’im.)

You may disregard any staining found on your underwear during the first few days after the procedure as it may be attributed to dam makkah. If it makes you feel more comfortable, you may wear a pantyliner.

Please feel free to get back to us with any further questions.

We wish you a safe and healthy pregnancy!
