I have been having issues with my cycle where i'd go a few years without it one, then be normal for a bit then back to the same. it has happened like this 3 times. what could cause ths? i wanted to get opinions while i'm waiting to get seen?

Your symptoms are consistent with pre or perimenopausal syndrome but this syndrome should not progressing that long with multiple, prolonged episodes of secondary amenorrhea then normal cycles. Diseases of the uterus do not manifest that way. Hormonal imbalance is likely the culprit but again you should not have normal cycles between amenorrheic epidoses. Good luck with your visit and take care.
