Three days late

Still no AF. And I haven't tested in two three days. I keep running to the bathroom literally every ten minutes because I feel moist down there. But when I wife its nothing but a Lil milky discharge. (No smell, no itch) could it be I'm preggers or just a late AF ? I am so scared to test because I don't want to see a bfn. And I'm still cramping. I just know AF is gonna show up. 😢😢😢😢 this is such a depressing process. I don't know what's worst. Waiting or getting bfn after bfn. And on top of it me and my fiance had our first argument ever. All his things are packed and call me crazy but I'm stuck between wanting him to stay and letting him go. I feel so overwhelmed, sad, and depressed.
