I presume you had attained menarche
normally and then stopped having periods from 16 yrs of age and you are 22 yrs now. If that is the cause , there is a possibility you might have a premature ovarian failure
. I would suggest you to get your hoermonal evaluation first to find exactly what is happening and then decide on treatmdent. Bringing periods is not a problem, but fertility
will denpent on your medical problem. An endocrinologist
can definitly help you.
