AF Due Today, Cervix so high I can't reach it!

For the past week I've been experiencing cramping, intermittent nausea, fatigue and moodiness. Still having cramping while I type this.
AF was supposed to come today. Went to check cervix and I literally could not reach it! I am also having watery CM with mucousy bits (TMI). I tested yesterday but BFN. When should I test again? Should I even get my hopes up?
