Is It Possible?

Hey ladies,

I was wondering, can an ovulation pick up your LH surge days before AF arrives I'm asking because I ovulated on the 19th on the 18th i got a postivie opk the test line was super darker then the control line and my opks were getting lighter after that. However I'm 1 day late and hpt are BFN, but I took another ovulation test lastnight and right now and it got darker, both the control line and test line are equally dark like positively dark.

But the question, can it become positive because AF is close ??
