confused

okay so last week I took this test because i thought I was spotting . Normally my period comes exactly on the 1st of each month. well last month it was a day early and this time it was 4 days early. Is this evap or faint positive. It was within 3 minutes of the test. Has anyone had a positive and still had a period? I don’t want to be pregnant at the moment , have to wait another 3 months before ttc. luckily I have a 9 months post treatment check up tomorrow and they check my hcg. however wanted to see thoughts on this test . i know blue dye isn’t accurate sometimes
