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. I have been having fertile cervical mucus 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, then you may omit the moch dachuk for the duration of your attempts to conceive.

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

You may also find it helpful to consult a Yoetzet Halacha Fertility Counselor. (This is a free service, details here.)
