First Postpartum Cycle — HELP!

I am on cycle day 21 (first postpartum cycle). Since January, I have had extremely cyclical EWCM (always on the 7th or 8th of the month). I did not have any June 7th or 8th. Did anyone have this with the return of their cycle postpartum? I am so thrown off since the EWCM has been the exact time every month for five months. Could I have ovulated sooner and had no EWCM? Or anyone ovulated after Cycle day 21 in first postpartum cycle?
