Bbt drop pinkish CM

So today at what I think from my chart is 7dpo I got a temperature dip and this was followed by pink (darkish) CM which is light but hasn't stopped yet today. I'm on day 27 of my cycle and would expect a 10 or 11 day LP

I have had this pinkish CM before and it was followed 2 days later by a full blown period, however I am also mega cranky agitated I feel dizzy when I stand up I'm fairly tired and on the verge of tears constantly. Also I'm having hot flushes. I guess it's just a waiting game now to see if AF comes?
