PLEASE READ... maybe another chemical😢😭

So at 8dpo I test and got a very faint positive. Today with flu, not diluted very yellow and concentrated, at 10dpo and either there is no line(BFN) or it’s too faint to even see. I need hope and prayers. I’m 4 days away from AF. Why would this keep happening. This is our third chemical if it is. My heart is breaking. Anyone. Have a faint positive midday and not test positive with FMU? I mean I know the line should be getting darker. Has this happened to anyone within a 2-3 day time frame and everything turn out fine?

This is 8 and 9dpo... this mornings test was BFN.
