Ovulating without having had a period?

I stopped my BC beginning of December and AF was 12/6. We did BD throughout my fertile week. My projected AF was 1/2 which still hasnt happened. Ive tested multiple times (as recent as Saturday 1/6) and BFN every time. The past couple of days Ive had EWCM and I believe my cervix is medium depth and medium opened, but I’m new to checking that. My bbt has declined the last two mornings. Could I be ovulating without ever having had my Jan AF? I know coming off BC does weird things...
