Tracking after coming off BC:

Hi! I stopped my last pack on 12/28 with my withdrawal bleeding on 1/1-1/4. I am now on CD20 tracking with OPKs and have no rise. I am trying to understand my cycle and CM is alllll over the place. Would love to hear similar stories! I have been off/on hormonal birth control for 10yrs (4 pregnancies and 2 kids). How late did yall ovulate after coming off the pill? I finally got my bbt in the mail and it was high 97.89° on 1/18 (missed 1/19) and was 96.54° this morning (1/20).
