i read you question and understood your problem. you are having problem with nabothian cyst
and bleeding. the reason for your bleeding may be due to that cyst. your tvs report showing uterus
,its thickness, both ovaries and cul de sac is normal. you have some issue with your cyst only. these cysts generally develops but dont cause any problems.
you didnt mention about any pain associated with cyst movement. mostly these cysts dont cause any problem . if at all problem there it is due to pain over cyst movement or touching and bleeding.. doctor already prescribed you the medication to stop bledding know ... so just use them and if symptoms subside you dont neeed to worry .. if not you have to undergo a minor surgery to incise the cyst.
hoping you dont need to go for surgery and recover with medications itself.. thank you
