Is this an EvAP?

Sophie

I am 1 day late for my period I was meant to start yesterday on the 30th September. I took a test in the morning around 11am an then one again at 6:45pm the one at 11am was negative but it wasn’t first morning urine an quite diluted the test in the evening was positive.

I am just wondering if this is a EVAP or should I test again?
