Periods after bc

Jaz

So I just got off birth control trip officially the 2nd week of Dec. My periods been weird. I started getting them in Sept. The end of Sept I had it for like 3-4 days they were pretty heavy. No period in October then I had a period Nov 12-15th, and Nov 28th -Dec 2nd (1 heavy day). Bleed again Dec 5th so I started taking birth control again then stopped after 3-4 days. lol Since then I haven’t had a period. For those that took the pills how long did it take to start having regular periods again?
