In PCOS, the ovarian cysts are always present? Like present in every sybsequent menstrual cycle? Or the ovarian cysts can come in some cycles and go in some cycles? I have undergone  ultrasounds, In month of december in which the report showed mutliple small follicles on both ovaries in one month ( on day 15) and report said PCOD is there, but in the next month, in january it showed normal ovaries with dominant follicle ( on day 15)
