So confused !?!? Helppp

I had my period literally last week it was fairly heavy but not as long as usual but I feel pregnant done 2 tests this morning both vvvvfl but defo there is there a chance it could be Evap line on two tests ?? Or could I be pregnant so confused I'm having cramps like I'm ovulating so I no if it was from This month is would defo not show up just yet. I'm sure once the test was left 15 mins the line has got darker but I thought Evap lines disappeared ??
