What do you guys think ?

So we bd every night during my fertile week , I didn't use opks this month I just went base off hormonal changes , mood swings and cm . I believe I should have started my period on Thursday .. We'll on Friday I had slight cramping so I though okay AF is fixing to show I went to the bath room and my cm has a brown color to it , we'll here we are in tuseday and still no period and Still having creamy cm / milky thick cm . I'm still cramping on and off , but no AF . normally around AF I'll get extreamly watery cm .. Or be COMPLETLEY dry .  I don't want the disappointment of another negative test :/
