Missing ovulation with 28-day cycle?
3 December, 2015
I am nervous that I am suffering from halachic infertility.
I have been trying to get pregnant for almost a year. I got pregnant very easily with my first, and I know other factors come into play, but since giving birth, my cycles have evened out to 28 days consistently.
When I gauge my ovulation, and look up ovulation calendars online, I see that I am missing my first night of fertility due to niddah.
I got my period on November 26th in the evening (November 27th). I can only do a hefsek taharah at the earliest on December 2nd. However, I will be fertile as of December 8th, the night before I go to mikveh.
I was wondering what one should do in this scenario, and if this sounds like possible halachik infertility, or if I have been unsuccessful for other reasons.
Ovulation usually occurs between 12-16 days before your next period. That means that if your cycles are around 28 days, you should ovulate sometime between days 12-16 of your cycle, which could be either before or after mikveh. You should not rely on ovulation calendars online, but should start using over the counter ovulation kits to confirm when you are actually ovulating.
If the tests show that you are ovulating before immersion, the first step is to make sure you are immersing as soon as possible. You state that you are unable to perform a hefsek until day 6. The hefsek taharah need not be completely clear to be acceptable. If you are not actively bleeding, you should clean yourself out thoroughly (in a warm bath, etc.) and attempt a hefsek on day 5. Stained bedikot should be brought to a rabbi for evaluation explaining that you are having difficulty conceiving. Not all stains will invalidate the hefsek or the clean days; there are many shades of brown which are acceptable.
If you find you are consistently ovulating before mikvah, and you are unable to immerse sooner, usually the next step is speaking to your doctor about medical treatments to delay ovulation. Please see our articles on diagnosing and treating halachic infertility for more details.
If you confirm with the ovulation kits that you are ovulating on or after mikveh night but are still unable to conceive, we recommend consulting with your doctor to discuss the possibility of a fertility workup since you have been trying to conceive unsuccessfully for a year.
