So confused...is it real???

Stefani

Is this an indent or an evap? I took this on a whim last night at 10:30pm along with an ovulation test. I don't see how this is possible, I never got a positive ovulation test and my period isn't due for another 5 days. And I took it at night! How is there a line??? Is it a real line??? How could it be real??? The first day of my last period was March 15th, this just seems too early.
