Can I Get Pregnant If Suffering From Polycystic Ovary?

Hi, I am 29 years old and where trying to have a baby for almost 4 years. My periods will only get normalize when i take duphaston but when i stop I go back to the same problem. I have been taking duphaston and clomiphne for almost a year but I suddenly stop 4 months ago coz it seems that it has no effect to me. And now, I got an ultrasound with my gyne and result was, I have a polycystic right ovary, cystic follicle at the left, slightly thickened endometrium and with intramural myoma at the upper posterior wall measuring 2.2 x 2 cm. What is the best medication for this and should I still have a chance to get pregnant? Is my condition worse? I am badly needed your advise. Thanks
