Omg so confused...

I had sex only one day last week on Sat well more like Friday night and I wad ovulating I checked, but anyways I ended up being so tired Today like to the point I can't get out of bed and I took a test.yeaaaaa I know what for because it hasn't been a week, but I think I see a line. It came in the time frame just how could this be with only sex 7 days ago?? It a dryer now and looks dried out cus I fell back asleep for a few hours but it hasn't gotten darker. Please opinions do you see a line or am I insane. Is it an evap? Does it look like a normal line if one is even their lol Faulty test? I'm so confused lol
