Af due tomorrow!! 9/25

So I took a test Tuesday in the morning. Negative. Took one today at lunch time, negative. I am going to test tomorrow morning or Saturday which is best do you all think?! Or Sunday?! Or just wait for af to not come at all? I'm so thrown off I don't have my usual period symptoms at all and my cm is milky. Or a lot but when I wipe and when it does come out its that way. I'm getting so down and anxious like am I getting a period or not!!!
