blue dye tests

i don’t know if i should trust these results, i took the first test and a line popped up around the 1 1/2 minute mark, a very obvious line. and then i took one later that night and had the same result. i didn’t use fmu with either of these tests and i have no idea how many dpo i am, and my period is supposed to start today but i always have irregular periods. should i trust these results and take another test? or should i disregard both results ? and if i do take another should i just use fmu or does it matter what time of day i take the test ?

first test

second test
