Please tell me your favorite brands for ovulation tests if you use them! I've been using Blue Cross for about 6 cycles now and they never get dark enough to be considered a solid positive and I think I need ones that are more sensitive to really pinpoint my ovulation. Because they stay faint for about 2 weeks and then nothing! Its super frustrating but I'm having trouble making my decision on a different brand. Any kind of input helps ☺ this picture is as dark as it gets for me
