I presume u have taken clomifene citrate for ovulation induction and u seem to be a poor responder to that as the dominant follicle is not forming.
In the light of ur history u seem to be having PCOS, so firstly atleast try to lose 5% i.e.3.5kgs of weight to begin with as tbe ovulation rates rise up drastically with that.
Exercise, cutting down on
sugar in tea coffee are some means of dietary changes.
Please consult an infertility specialist (a general obgy may not be of mch help) as u need to be given inj hMG or rec
FSH if u do not respond to basic ovulation induction drugs.And go for follicular monitoring and IUI, perhaps.
It is mainly a lifestyle disorder so eat fresh veggies,flax seeds, say no to packaged foods n soda, sugar, biscuits, processed foods etc.
U need to be started with Tab DHEA and myoinositol as they improve micro follicular environment under supervision.
No smoking and alcohol if any, strictly.
U cud hv attached the discharge card so as to knw if there was any lap ov. drilling that was done if at all there was any bulky ovarian stroma as in pco.
If u hv taken back to back 5 unsuccessful induced cycles then take a step back and rest for 3-4 months.Chances of conception in abandoned cycle is high!
U need to tell us ur
AMH to knw the fertility, anyway i presume u r still 31 and u will conceive sooner or later.
Goodluck.
