hello doctor,

my LH was 10.9 mIU/ml
my FSH was 8.67 mIU/ml
my prolactin was 11.9 ng/mL
my TSH was 1.29 uIU/mL
i underwent testing on 2nd day of my periods.
initially i weighed 72 kgs, i am now 66kg.

i have also suffered a misscarriage before 6 months.
i have been taking
metaphage : 500 mg each after lunch and dinner
evening primrose oil : 500mg after breakfast
clomid : 100 mg from 2nd day of cycle for 5 days
duphastan : 25mg twice from 25th to 30th day of my cycle

after taking so many tablets, neither i concieve nor i get my periods on date.
i used to undergo follicular tracking, but still my periods used to get delayed.
sometimes upto 7 days.
