Ovulation Test strip confusion

[Holler90]

For 3 days in a row I have gotten what I would call an almost positive. The control line is dark pink, and the test line is just a shade lighter. I tried to upload a picture but it said "file to large." What does this result mean?

The test line must be exactly the same colour as the control line or darker than the control line.
