When Do I Start Testing for Ovulation?
Ovulation Predictors >> When Do I Start Testing for Ovulation?
Luteinizing hormone in elevated
quantities causes ovulation. During the menstrual cycle only a small amount
of LH is made, but in the middle of the cycle LH briefly and dramatically increases.
This increase is called the "LH surge" and precedes ovulation. Conception
is most likely to occur within thirty-six hours following the LH surge. The
LH Ovulation Test is specifically designed to detect your LH surge - the time
when you are likely to ovulate. To
determine when to start testing for ovulation, follow the instructions below:
1. Determine the length
of the menstrual cycle. The length of the menstrual cycle is the number of days
from the first day of menstrual bleeding to the day before bleeding begins on
the next period.
2. Determine the usual length
of the menstrual cycle over the last few months. Then, refer to the Ovulation
Calendar Cycle Chart below to determine on which day of the menstrual cycle
to begin testing. If your cycle is less than twenty-one days or greater than
forty days, consult a physician.
