I was on it for approximately 7 years after being diagnosed with PCOS. Never had any issues with being on it. Periods became regular and lighter and my skin was relatively clear. Had the usual spot on my chin every month but that was about it.
I didn't notice a major difference afterwards but my skin did get worse with spots and more oily, realised it was affecting wearing contact lenses and my periods were back heavy, bad cramps and feeling sick. Gained weight coming off it as well.
Cycle return to normal
