In polycystic ovarian disease
(PCOD) there are multiple cyst on the ovary, here the periods become irregular as they are anovulatory cycles (ovulation fails to take place). oral contraceptive pills
regularize the cycle by causing ovulation. u need to continue crisanta
untill ur cycles gets regularize. Medical management should be supplemented with ultrasound
scan and lab investigation (FSH and LH harmone estimation) for periodical progress. weight reduction, controlling blood sugar level and regular exercise will be useful. take care...bye...
