Gonna sound dumb bare with me

So I know it's best to take a test in the morning, for first morning pee or whatever. But I stay up all night and don't sleep until 6am, and wake up until 4pm. Crazy I know. work throws me off. But does that mean I should take a pregnancy test before i go to sleep since it's technically morning? or wait till I wake up at 4pm, for best results? I know I sound dumb but.. lol
