OK so I have PCOS, diagnosed 10 years ago. My periods have always been very irregular but the last 2 years things have got better.... instead of waiting 50 days one period and then 215 the next they've been around 48 days and usually last for around 8/9 days. So this period came- and I started taking soy isoflavones on day 2 till day 6.... we are now on day 17 and my period is still happening... has anyone else experienced this???
