Ovulation help please!

Em

Yesterday on CD 16 I had very high OPKs, but not quite positive (see photo). Today my OPKs are low again. Lower than they have been in the past week. Does this indicate that I am ovulating/will ovulate today or is it more likely that my body prepared to ovulate and failed?

I am on my second cycle after quitting BCP 4 months ago. My first cycle was 93 days, anovulatory, and progesterone induced period.

This is also my first cycle using OPKs and charting BBT. I began OPKs on CD 7 and they started getting darker on CD 11.

On CD 12 and 13 I had very fertile egg white cervical fluid. On CD 15 I began experiencing very light brown spotting only when wiping and yesterday (CD 16) brown spotting mixed with egg white in the am and more creamy in the pm. TIA 🙂
