Hello madam, from the history you have given, follicular size must be around 18 to 20 mm, which is the mature graffian follicle.Well depending on the complete history and treatment history, your doctor must have suggested you ovulation inducing agents like Clomiphene citrate or gonadotropins. Since you said you are under treatment for 2 months, you can still try using the ovulation inducing in agents after consulting your doctor..Clomiphene citrate can be used uptill 6 cycles; thought most of them conceive during first 3 cycles.In case of Clomiphene citrate failure then gonadotropins are next choice which is generally followed.But the treatment depends only after a complete history, examination,regular follow up and rulling out any underlying pathology and depends on expertise.hope I was helpful to you.
