I have gone through your query and understood the concern. Your sonogram report states that you have a bulkier uterus
and also the thickness of the endometrium is much more than normal. This is suggestive of unopposed estrogen
activity. Considering your age, proper investigation including clinical evaluation and hormone assay is needed to detect the extent of hormone imbalance
an to help plan further management. This is to attain good fertility
status as you are advancing in age. You will need progesterones to control the endometrial thickness. Hope this helps.
