Please tell me I'm not crazy

I was taking the blue dye tests and they were barely there faint. Everyone recommended a pink dye, and still barely there faint almost a pale pink to the naked eye. I even opened it because I thought my eyes were just seeing what they wanted (I know you're not suppose to but all these faint lines are driving me crazy). one minute I feel like af is coming then another minute I don't. I'm going to test again in a few day, but opinions would be appreciated.
