How long does it take for a luteal phase to drop?

It is normal for temperatures to drop about 12-14 days into the luteal phase (the day or two before the period) – this indicates decreasing progesterone levels and the onset of menses – but if BBT drops rapidly and continuously after ovulation, Kidney yang and Spleen qi tend to be deficient (See Figure 2.7). In this case, the length of the luteal phase is adequate, but declining temperatures reveal another weakness. If a higher BBT is not being sustained (e.g., low progesterone levels), this indicates that Kidney yang is in decline; there may also be spotting, indicating that Spleen qi is unfirm. Treatment will involve supporting the Kidney and Spleen during the luteal phase.

How long does it take for a BBT to surge?

Traditional Chinese medicine classifies this pattern as Kidney yang deficiency combined with Spleen qi/yang deficiency; Liver qi stagnation may also be a factor as it has a tendency to impede timely ovulation. Treatment to support the Spleen and/or Liver early mid-cycle, and Kidney yang in the luteal phase is recommended; reinforcing Kidney yin at the beginning of the cycle may also be helpful.

Why is my luteal phase low?
