Wondfo Tests - what’s the earliest you’d test?

Lily

I’m only 6dpo and will be trying my hardest not to test until at least 12-13 dpo! But I have Wondfos (the cheap strips) and just noticed they said they can “detect as early as 3 days AFTER your missed period”. So now I’m wondering… what’s the earliest you’ve gotten a positive pregnancy test using Wondfo?
