Im supposed to be at my most fertile today and tomorrow. I keep doing opk tests and its not getting darker. They are kinda getting lighter.: ( the first pic was on the 12th at 1:45pm

Second pic was same on the 12th at 10:45pm

Third one was just right now (14th at 10:30pm)

I've been spotting a lot but I always spot a day or two during ovulation. Last month on the 19th I got a very positive opk test so could glow be off on my days? Im so confused and NEED this to be our month!!!!!
