I know how hard it is to wait, the anxiety of the two-week wait is so real. But for the most accurate result, try to wait until at least the day of your missed period, or even 1-2 days after. Testing too early can sometimes show a heartbreaking negative even if you are pregnant.
It is best to test 1 or 2 days after your missed period date to avoid confusion. If you get a faint line or have any severe cramps or spotting, please don't wait for another home test, just go directly to your gynac for a blood test.
I am also in the same boat right now, counting down the days! My friends told me that testing exactly on the day of missed periods is best, especially with the first morning urine [1.1.4]. Are you feeling any symptoms yet?
Honestly, wait until your period is actually late, otherwise you'll just waste money buying 10 kits like I did! And please do it first thing in the morning when you haven't had water yet, or your pee will be too diluted to show anything.
Oh my god, I used to test like 5 days before my period and then cry when it was negative, then test again the next day! Save yourself the mental torture and wait until you are at least 3 days late. It is so hard to wait, but the result will be much clearer then.
