If I recently started having regular menstrual cycles at 17 does it mean im done with puberty now?

? started menses. Pubertal hormonal and growth changes continue for about 2-3years after the onset of menses. So if you just started menstruating at 17 (that would be king of late) then puberty wouldn't be complete until around 20. However, if your periods started when you were 14-15, even if they weren't regular at that time, then you are indeed nearing the end of pubertal development.
