I am using the First Response Digital Ovulation kit AND the normal First Response Ovulation sticks. 2 or 3 days ago I started seeing the lines on the sticks progressing. Last night the lines on the stick test were ALMOST the same color. I took another stick test today at the same time I took my digital test. My digital test came up negative and the stick test came up positive, with the test line darker than the control line. Has this ever happened to any of you ladies?! Not sure what to think!
