Hi, I am 29 and I have never been pregnant. I have had an ultrasonography recently and they discovered that I have an endometrium thickness of 19,2 mm. The doctor said this can be endometrial hyperplasia. I have had regular menstrual cycles so far, the last being on the 17th November. Then on the 5th of December I had some dark-brown even black spots that lasted for 5-6 days. After 10 days, I began having by 1-2 drops of blood each day. now they stopped, but my menstrual cycle hasn't come yet. What might my problem be?
