Opk madness......

Barbara • 12 yo dd, gave up on any more 💔
This is so frustrating. I feel like there should not be 2 lines on an opk constantly. None of these lines look as dark as the test line and they are ranging from cd 8 to cd 19. I did miss 2 days (17&18) and have taken 2 today cause I feel like they should be getting darker. Opinions anyone?
