Thanks for the query to H.C.M. Forum.
No , you are not going through menopause
But one thing is very important for you, that you were a patient of PCOs , you haven't mentioned ,when you operated for P C O S?
2nd point is that usually poly cystic ovarian syndrome , as its name indicates , have multiple cysts
, so please again get in an ultrasound
of both sides to find out any other cysts.
As in P C O S, there are hormonal
imbalance, that's why patients develops amenorrhea
or scanty blood during period.
If possible upload the report of ultrasound over this site.
Hope I have answered your question.
If further any question I will help.
Get well soon.
