hi.. you have PCOD, irregular periods
and not able to conceive.. probably you are having anovulatory cycles.. you need to undergo certain hormonal tests like FSH, LH, Prolactin
which is done on the day3 of your menstrual cycle.. thyriod profile and AMH anytime during the cycle.. ultrasound
examination on day3 for antral follicles. after that the hormones should be regularised with drugs and then try with ovulation induction
. see your gynaecologist for this..
all the very best..
