Test help

So last Friday I took a cheap strip test, ?positive? Image attached... I then since have done a clear blue and first response and negative on both? I don’t know when my period is due because I haven’t had a period since November. I was on the minipil and stopped taking this 30th December. Iv only had sex 3 times since 30th December unprotected ( 5th jan, 11th and 12th jan). Do you think this is a false positive or a evaporate line? As I know if I was pregnant it would be very very early on?
