Luteal Phase

Luteal Phase
The luteal phase is the time between ovulation and your period. Progesterone is the dominant hormone 
during your luteal phase and is produced by the corpus luteum (remaining follicle after ovulation). 
Progesterone is a heat producing hormone which is the reason we see a rise in BBT after ovulation. 
Progesterone production typically decreases a few days before menstruation starts and without the 
support of progesterone, the endometrium (uterine lining) starts to break down and menstruation will 
start. Your luteal phase should not vary more than a day or two if ovulation is detected correctly. 
A typical luteal phase can last anywhere from 11-16 days.
Women with a luteal phase of 10 days or less are said to have a luteal phase defect which may or may 
not impact on implantation. 
If you feel your luteal phase is too short seek guidance from your general practitioner or medical provider.
