Now we get the cm?!?!

Maria
Ok I'm beyond confused...
AF veryyyyy light/ spotty 10/10-10/12.
Stopped bc pills this month. Last blank 10/15
Started taking opk and got positive on Sunday 10/19. Bd 4 times during my fertile window.
Got a second positive opk yesterday at 9 dpo
Now today, no more positive opk, but I got a good amount of egg white cm when on the TP. I've been pretty dry the whole month ( I normally am). 
Please help! What's going on?!?!
