God Himself made woman in such a way that post-ovulation progesterone causes her waking temperature to rise enough that it can be readily noticed with accurate temperature taking and recording. A sufficiently elevated temperature pattern of at least three days provides a positive indication that she is past ovulation. Every man and woman deserve to know this aspect of God’s creation.

God made natural signs for determining fertility and infertility.
God Himself made woman in such a way that pre-ovulation estrogen causes a healthy discharge of mucus from the cervix and also causes several physical changes in the cervix. Both the mucus and the physical changes of the cervix can be detected and evaluated by informed women. Every man and woman deserve to know these aspects of God’s creation.

God Himself made woman in such a way that frequent suckling by her baby at her breasts postpones the return of fertility for more than a year in most cases. This is not an old wives tale. Scientific research has demonstrated that the frequency of suckling is the key to the normal postponement of fertility. Mothers who practice ecological breastfeeding according to the Seven Standards will experience, on average, 14 to 15 months of breastfeeding amenorrhea (the absence of periods). They will also give the best nutrition to their babies, and with each baby they will save over a thousand dollars by not using formula and baby foods. Finally, they will gain health benefits for themselves as well as for their babies. Every man and woman deserve to know this part of God’s creation.
I know that these statements will meet with skepticism by some, so I invite you to review our research published in 1972 and 1989 plus a summary of the research published up to 1972.
