thanks for your query.
I hope you are having proper evaluation and treatment for PCOS, as apart from irregular periods
, it causes lots of other conditions like impaired blood glucose, thickening of lining of uterus etc.
Please do not take any medication without guidance.
Go for a check up, and have all hormonal tests done, and then the best option for bleeding is to have norethisterone
However, let your gynecologist decide the dose and the regime to be given.
After that you can start oral contraceptive pills
, they would contribute to regulating your menstrual cycle also.
