Ovulation tests question

So this is my first time using the test strips to track ovulation. I haven’t had a for sure positive like dark dark test line. They’ve been close though but out of all the days I’ve tested starting at CD4 and today being CD15 I haven’t had a super faint line like this. Did I drink too much fluids or is it just decreasing? Oh and the side next to the control line hasn’t stayed dark like that either.
