Did she typically have a luteal phase (time of elevated BBT between ovulation and beginning of next cycle) of at least 10 days?
RAH – One of the “hidden” types of infertility is a luteal phase that’s not long enough to allow the fertilized egg to implant in the unterine lining. In other words, the egg is successfully fertilized by the sperm, but by the time this zygote (fertilized egg) makes its way from the Fallopian tube down to the uterus, the uterine lining has already begun to disintegrate, in preparation for ending the cycle and menstruation. A short luteal phase, [sometimes unfortunately called luteal phase defect (LPD)], is not hard to detect if you are monitoring BBTs. The guideline recommended in TCoYF is that you should have at least 10 days of elevated temperatures after ovulation. Authorities vary on “how short is too short”; some authorities believe that a luteal phase of 12-13 days can be problematic for fertility. As you will see below, there are different opinions about “how short is too short” on the newsgroups as well. Certainly a luteal phase of 14 days seems adequate for most; on the other
