Hello and welcome,
The size of the cyst
is 12 millimeter which is very tiny to be concerned about. It is most likely an incidental finding. Also the bleeding you are having is not unusual in the menopausal age. There is no strict definition that women with an FSH of 99 must not menstruate. It is that they are less likely to menstruate.
However it is advisable to get a D and C done to rule out any possibility of an underlying problem. So you may get it done. If the cyst is 12 mm and not 12 cm, there is no need to worry at all. Just get a repeat scan after 3 months to see if it is increasing in size or has disappeared.
Do not worry, these are common issues during menopause
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
