The color intensity of the test bands may vary due to different concentrations of HCG at different stages of ovulation. If you start testing as early as 4 days before cycle day 1, bear in mind that your body may not yet produce enough Hcg for a positive test result. Use first-morning urine for the LH pregnancy test because the concentration is the highest right after you wake up.
