If you are using Clomiphene Citrate (e.g., Clomid® and Serophene®), consult your physician for possible interference with the test.Some rare medical conditions and/or the onset of menopuse can cause elevated LH levels. To determine your results, compare the color intensity of the test line to the control line as follows: Positive = LH Surge: If 2 lines are visible and the test line is similar to or darker in color compared to the control line, your LH has surged and you will probably ovulate in the next 12 to 36 hours.Some negative results may later display a faint test line due to evaporation from the testing zone.Therefore, you should not read the results after 30 minutes and discard the test once you have read the result.
Your menstrual cycle length is the number of days from the first day of your period to the last day before your next period starts. The chart shows to start testing on cycle day (CD) 11.
Q: Once I see a positive result, when is the best time to have intercourse?
A: Ovulation is likely to occur within 12 to 36 hours. Sexual intercourse within this time frame is advised.
Q: I am now using the basal body temperature method (BBT). A: The BFP Ovulation Test Strip may replace the BBT method if you choose or may be used simultaneously.
The shift in basal body temperature primarily indicates ovulation has already occurred.
