Welcome to Healthcare Magic
Please provide details about your periods. How many days is it usually for. Since when did it change. You have probably gotten this scan a few days after your periods have stopped. The thickness of the uterus
inner lining is quite normal and there is a follicle which will ovulate soon when it becomes around 20mm. You need to get your Thyroid
hormones checked if your periods are irregular. Also get LH/FSH ratio done. From the scan nothing is confirmatory of any problem as yet. It would be better to get further investigated ti rule out PCOD
and Thyroid problems.
