Confused 😐

Sam
I'm wondering if this could be my month! 
I ovulated around CD18 and AF is due tomorrow CD31, but weirdly other than being a bit more emotional than usual, and a single pimple, I have no symptoms. ZERO!
I usually suffer with super sore breasts, bloating and sugar cravings. This month absolutely nothing. 
I've been getting sensations in my lower right stomach but they're not cramps and yesterday I had white stringy cervical mucus. 
I took a test on Wednesday but it was negative. Any thoughts ladies???
