When to test?

Br

My period is due in 2 days, I have just barely a little pink in my discharge when I wipe. How soon can I take a pregnancy test? I know they say the day after your missed period, but I’m so anxious! I have one test left, and I have to wait until the weekend for the rest to be delivered 😬 thanks in advance!!

Update: period came a day early right after I ripped open the last test🙃
