Documenting Ovulation with Quantitative Basal Temperature (QBT)

If our cycles are regular - about a month apart we assume we are ovulatory - meaning releasing an egg and making normal amounts of progesterone. However, ovulation is highly variable for all women. Progesterone raises our first morning (or basal) temperature a little bit. But so do many other things. Thus "basal body temperature" (BBT) charts, even with mid-cycle stretchy mucus (symptothermal methods) may not be accurate for predicting ovulation. Therefore we developed a valid and scientific use of basal temperature called "Quantitative Basal Temperature" (QBT) to assess ovulation and the luteal phase length (number of days of progesterone elevation).
