does it matter what time during the day you take a pregnancy test?

I had heard to take them in the morning, is that correct or does it not matter? I've never taken one before but I have one laying around for emergencies and want to take it to ease my mind bc I had sex at the end of May, got my period mid June, but I'm now 8 days late for my period this month (I haven't had sex since that time in May and my cycles are very short). can I just take it now (it's 8pm)? I'm worrying myself sick even though I know it's VERY unlikely. I can go get another test if need be but I kinda wanted to take one rn, I won't take it now though if it won't be accurate.
