Hi . I was suffering in periods irregularity. Some times gap between my periods 2 months some times 3 months. I started tab cypradol on 5 th days of my menses and for 21 days . After taking 4 tablets started abdominal pain and nausea. And that’s why I stopped medicine. Now after 8 days again my periods started.
