Luteal Phase ... How to count the days?

Although I feel I'm quite versed in the ways of my monthly cycle after reading TCOYF, I do have a question about luteal phase.

Here it goes. I always thought that the LP was the DPO that FF gives you. Which starts counting the day of the first temp rise (so the day after O). That would give me a 10 day LP. My doctor looked at my charts and said I have an 11 day LP. She counts the day of O as well as part of the LP.

How have you and/or your doctor counted your LP? Although I hate being wrong, I'd love to have my LP as 11 days. I would then have a normal LP!!!

TIA for your input!!!

In both TCOYF and FF, I've always seen LP counted like you count it, starting with the day of the temp rise.

I'm not sure so I started searching the web.

This site says it starts "at ovulation".

http://www.ovulation-calendar.com/hlp-d04-luteal-phase.html

"The luteal phase, also referred to as 'days past ovulation' or 'DPO', is the part of the cycle that starts at ovulation and ends the day before your next period. It usually lasts about 14 days and does not vary by more than a day in each person. The luteal phase is named after the corpus luteum (Latin: "yellow body"), a structure that grows on the surface of the ovary where a mature egg was released at ovulation. The corpus luteum produces progesterone in preparing the body for pregnancy. Your luteal phase must be at least 10 days long to support pregnancy."

I interpret this to mean starting the day of ovulation.

http://www.inciid.org/lpdefect.html

"The luteal phase of the menstrual cycle spans the time between ovulation and the onset of the next menses. Luteal phase defect (LPD) is a common but misunderstood condition that frequently affects fertility."


It seems to me that it varies. I wonder if dpo=luteal phase or not. If luteal phase includes the day of ovluation but dpo (as the name describes) is the day after O then it would seem these two indicators are different.

Goodluck!
