After stopping BC

Hi ladies, how long if any of you did it take for you to start seeing your cycles get back on track after getting off your BC. I've been off the pill since January of this year and Ive had irregular cycles since going off of it, making my ovulation hard to track each month. 😕 Before when I was on BC I had normal same length cycles (28 days). Im just wondering if maybe I'll go back to ever having regular cycles again? Or the BC is still working its way out of my body as I was on it was 11 years before I stopped taking it. My cycles now range anywhere between 29 to as long as 44 days.
