Currently on CD 16 of first AF after having DD (over 2 years ago - was delayed due to breastfeeding).
Anyhow, my cycles pre-DD were 30-33 so should be approaching ovulation. Yesterday and the day before I've had proper EWCM. Think my cervix is high as I could barely find it last night. Temps are still low and have remained low since AF so have not ovulated yet. I would have thought things were gearing up BUT CBFM says that I am not even having high fertility. 
Last night was a terrible night with limited sleep thanks do DD screeching and I drank loads of water because I was up and had a sore throat so maybe it's diluted...?
Has anyone experienced something like this where their body is telling them they are getting closer to ovulation but OPK says no?
