Went for first u/s today. Hcg is at1743 my first hcg on 6/26 was 22 so the numbers are going up as anticipated but the sac is located high in the upper left of my uterus near tube. I go back again on Thursday. My Dr says that he is concerned if the sac continues to grow toward the tube and/or top of the uterus. Had anyone experienced anything like this? If so I would appreciate your feedback. DH and I have had 1 mc and failed IVF..this was a miracle conception naturally. Praying for positive news.
