Tiny spot on moch, trying to conceive

15 January, 2017


I did a hefsek after five days of bleeding.

On the moch however, there was a tiny pinprick of red/orange.

We are trying to conceive and it took a year with our first and I have been having fertile cervical mucous before Mikvah. Is there any leniency in this moch or is it 100% necessary for the cloth to be evaluated?

Thank you


We appreciate the significance of this question.

There may be a possibility of treating this moch leniently, but that depends on having it evaluated.  Be sure to mention your concerns about conception when you have it evaluated.

If you find that you frequently have a successful hefsek taharah, only to discover something tiny invalidating your moch dachuk, you may omit the moch dahuk for the duration of your attempts to conceive.

For the next couple of months, you may find it helpful to use ovulation predictor urine tests (available over the counter in pharmacies) in order to pinpoint your timing of ovulation.  If you remain concerned about the possibility of ovulating prior to mikveh, please see our article "Halachic Infertility" and please don't hesitate to be in touch with any further questions.
