What is the mid-luteal phase?

For the CardioStress Plus test, females who have menstrual cycles must collect their samples during the mid-luteal phase of their cycle. The mid-luteal phase is normally 5 to 7 days after ovulation or day 19, 20, or 21 of a normal 28-day monthly cycle.

If you do not have a period, take your temperature daily. Collect saliva 5 – 7 days after
your temperature increases (an indication of ovulation).
