luteal phase

How do you count to determine your luteal phase?  Do you start the day after ovulation and count until the day OF your period? Or from the day after ovulation to the day before your period (I read this somewhere)?  
I think my phase is short but my dr is dismissing my concerns. It would explain a lot...
Thanks!

Starts the day that you ovulate and ends the day before AF shows up.  Also you can use this really neat calculator at http://www.mymonthlycycles.com/lutealcalc.jsp

Your luteal phase is frequently referred to as DPO or days past ovulation. This is the period of time from when you ovulate until the day before your period begins. In most women, the luteal phase lasts 14 days and does not vary more than a day less or a day more in the majority of women. Hope this helps =0)

My Dr. counts from day after LH surge (so likely day OF ovulation) to day before AF. My temps don't normally rise until 2-3 days after LH surge but he said that doesn't matter. Good luck!
