I usually take birth control pills sometimes. I was told not to take it no longer than six months at any one time by the docter. Now ah days I only take it when my period runs for longer than a week. But i will check on the Metformin.
Are you being treated for your PCOS? I'm taking birth control and Metformin. Both of these in combined are keeping my period in check. It comes on the 6th inactive pill and by the time I'm ready to start a new pack on a Monday...my period is just about gone. You will not know how your cycles or ovulation times are because us girls with PCOS normally do not ovulate. You should really talk with your doctor about starting Metformin. In time, it can produce normal periods and for some it can result in spontanouse ovulation.
