Af 3 days late!

Jennifer
I know that no one can say for sure but just wanting to hear people's opinions. Af is 3 days late and I took a  PT 2 days ago and a very thin line showed up. Most everyone on this app says its just an evap line bc it has color but it's thin. But what concerns me is the whole entire week before af was due I had spotting which I never do and now she hasn't showed. Anyone ever had spotting before an expected period and if so what was my from? I hoping the evap line was really a bfp but now I'm just to worried
To test again. Opinions anyone, please!
