To say that this product is life changing is an understatement. I was put on the OCP at 14 because I got my period twice a month and it lasted for 10 days each time. 35 years later I learned the negative impact of OCP and wanted to come off it. My periods again came back twice a month although not as long or ferocious, my moods were horrendous and I didn’t even recognize myself during PMS. I started taking another PMS product but it made no difference to either my periods or PMS. And then I tried this... WOW! My PMS has gone - no anger, pain or anxiety. And incredibly, my periods have regulated to once a month on a 27 day cycle and lasting just five days. I can not recommend this enough.
