Faint Line

Anna

So I am supposed to start my period tomorrow. I just took a test (end of day, diluted urine, no hold) and I see a VERY faint line. I figure it’s negative because if I was pregnant, since I’m so close to my period, I feel like it wouldn’t matter if I took it at the end of the day with diluted urine. Shouldn’t the hormone be strong enough by now?
