Am I missing my fertility window?
September 19, 2012

Question

My mikva night is set for tomorrow night and my ovulation date, according to my calendar, is today. We are trying to conceive – and how is that possible if we cannot have relations on my fertile days before ovulation? Typically my period lasts 5–6 days and mikva night is right before ovulation. But lately it hasn’t been working out. Any advice?

Also, I am pretty preoccupied in thought about the proper time to conceive, and I’m always checking for signs of pregnancy. It’s making me rather crazy, and I have no reason to be as we have no medical issues and have only been trying after going off Loestrin three months ago. However, since I am preoccupied, having relations is forced for me and all I can think about is if it’s going to work this time….forget about trying to enjoy myself.

Especially since my ovulation works out after mikva, it gives me another reason to worry.

Thank you for your guidance.

Answer

Thank you for reaching out to us.

It is not uncommon to feel anxious and preoccupied about getting pregnant. It may be helpful to bear in mind that it is normal to take up to a year to conceive (learn more here). For couples over 35, we recommend seeking medical advice after six months of trying.

We understand your concern about ovulating before mikveh. It sometimes takes a few months for the menstrual cycle to regulate after going off the pill, so it is possible that your cycles and ovulation date will readjust on their own.

It is advisable to make sure you are getting to mikveh as soon as you can - both to reduce time in niddah and to ensure you are not missing ovulation. The hefsek taharah need not be totally clear – there are many shades of brown that are acceptable. You can perform a hefsek taharah as soon as the bleeding is no longer reddish, and bring any questionable bedikot to a halachic authority for evaluation.

You state that your calendar indicates ovulation a day before mikveh. For future cycles, you may want to track ovulation with over-the-counter ovulation kits available at the pharmacy, or try some of the techniques of the Fertility Awareness Method to identify your fertility window. Learn more here. Keep in mind that cycles often shift from month to month.

In addition, a woman’s fertility window generally extends from 3-5 days before ovulation until a day or two afterwards (learn more here), so you may be able to conceive even with mikveh shortly after ovulation. You can learn more about ovulating before immersion here.

Some couples find that concerns about conceiving detract from marital relations. It is helpful to openly communicate your feelings and think together about ways to refocus on enjoying sexual intimacy and the love you share. Spending time together and investing in your relationship can foster feelings of closeness, and help you appreciate physical intimacy without worrying about conceiving. You may also want to seek counsel from a professional to help you reduce the stress you are experiencing.

We wish you much hatzlacha!
