i have had friends that have missed several periods for many reasons including low weight obesity hormonal imbalance menopause cysts and tumors. it's best to see a gynecologist to make sure the more severe of those options are not the cause.
what causes a period to stop for six months or more three years in a row? . i am 25 and over weight and have been since middle school. i am healthy and eat regular meals i exercise moderately and my stress levels are average. three years ago i missed my period for 8 months and when i started to flow again it was extremely heavy for one day and spotting for three days for every cycle. the days in between my cycles were irregular. seven months ago my period stopped again but for both skipped cycles i still get cramps and back pain as if i were on my period.
