Need Help with Ovulation tests! Please!

Help! (FIRST TIME USER OF ovulation tests) So this is the 4th ovulation test I've taken, in 4 days and the test band is STILL this shade, not matching the control band. I'm confused, does it mean I'll be getting my positive soon, like since the test band is appearing, tht doesn't mean I've missed it already does it? I know this is a negative result, jus confused if a Positive is coming or not. Btw I'm at cd19 but my cycles are and have been weird since my MC in July. First 2 were on time, 27 day cycle, but the 3rd one was a week late.
