When to test

So, AF is scheduled to come in 4 days. I took a digital test this morning. It sadly came up negative. Do I bother peeing on the stick tomorrow? Or just wait? I have been anxious, I thought for sure I was having symptoms... I know the closer you wait till your period the more accurate.

I am trying to not be down about this. If I could afford 4 more tests I would but they are so expensive
