Idk is this possible

I feel like my line on the first response ovulation test is lighter today than yesterday, but at the same time my body has ewcm so? Is it normal to have a dip before getting a positive? Ugh maybe I diluted it or something. I should be ovulating tomorrow based on the app. Last month it was right at 14-15 day. I hope it happens tomorrow because the timing worked out perfectly for us to bd on the highest percentage day 🤞
