I would wait a month after your expected period date. Just because the hormones are more strong the longer you wait. I tested that week after my period was supposed to come and it said no but I waited a month after and turns out I was pregnant. Also take it with your first pee in the morning. Just pee in a cup, stick the test in it for like 10 - 15 seconds (count slowly) then put it on the counter. Turn it over so you cant see it and walk away. Go wash your hands in another room, sing one song in another room, then go back to look at the test. I say do those things because it takes a little while for the test answer to come up. It will help calm you down while doing those things rather than staring at the test till the answer you want comes up.
