Took this picture of this probably evap but not sure cause I tossed after the control lines showed

Took this one after I discovered the first one and it’s in time but the line I see isn’t pink it’s yellowish... period not due until next week but I had a brown snotty bleeding spell (wipes it twice) a few days ago and my period last month was very weird... It lasted 5 full days and then stopped one and spotted 5 more... I actually got pregnant with my first the last day of my period....still having pretty bad cramps for the past 2 days and my back hurts... I know these are not good signs of pregnancy and these tests aren’t positive I’m sure but what the crap is happening to me?
