Missing ovulation with 28-day cycle?

Ovulation usually occurs between 12-16 days before the next period. With cycles around 28 days, it is possible that you are ovulating prior to immersion. In order to clarify whether this is the case, we suggest a combination of FAM techniques (see more here) and of ovulation tracking with a urine test kit.

If it turns out that you are ovulating before immersion, the first step is to make sure you are immersing as soon as possible.

For starters, it may be possible to get an earlier hefsek taharah, by cleaning yourself out thoroughly (in a warm bath, etc.) and attempting a hefsek on day 5.The hefsek need not be completely clear. Brown lighter than coffee with milk, with no reddish tinge, is acceptable with no need for expert evaluation. Any questionable attempts or bedikot (e.g., darker brown) should be brought to a halachic authority for evaluation explaining that you are having difficulty conceiving.

You can find more information about ovulating prior to immersion in our site’s article, here.

In any case, since you have been trying to conceive unsuccessfully for a year, we recommend consulting your physician for a fertility work up.

Please get back to us with any further questions.

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

B’Hatzlacha!
