Help! 3 days late and negative test!

Melanie

I'm currently 3 days late for my period I took a test this morning and it was negative I have read that you should wait a week after your missed period to take a test to have very accurate results but I also know that some people get a positive test the day of their missed period or a couple days after they're missed period. So is there any hope? How many days after your missed period did you finally get a positive test? Thank you in advance!
