Went off BC months ago, still waiting for period

Took me four months to get my first period after the implant removal.. then they where very irregular after that I would get a period ever 3/4 where before birth control I was regular 32 day cycle for nearly 10 years. I’m now on metformin to keep cycles regular which they have been since March cycles every 27/30 days. It can take months for your body to regulate or even get a period after birth control for many women
