is of concern when you are planning a pregnancy. if get delayed or irregular periods you have to find out if you are ovulating or not,also some hormonal tests (serum lh,fsh on second day of period, thyroid profile, prolactin
) need to be done. also your progesterone
level needs to be checked once ovulation is documented. you will also need to get a sonography
of the uterus and ovaries done.
