Very thin endometrium

Jessica
I just looked up my ultrasound results from last Thursday and it the transcription states my uterus and ovaries are normal in appearance but I have "very thin endometrium". I do have PCOS and my cycles are getting more and more irregular and painful but the are much shorter and lighter. (My last period was July 24th and this one started Oct 21st). Have any of you experienced this? What does it mean and how is it/ can it be treated? Any successful pregnancy stories?
