Trying to Keep from Cracking

Well, I went in to get wanded this morning and the news is decidely mixed. I am 5 weeks 1 day today. There was a visible amniotic sac measuring 4 weeks 5 days and a yolk sac measuring 5 weeks 2 days. Dr. Cookie Pie said the yolk sac had a "hat" ( a tiny white line on the border that indicated early growth of the fetal pole) and that such a line does not develop before 5 weeks 2 days. She said that the am sac measurement was within the margin of error and that I just should not worry. But I feel like I am going to crack from anxiety. I am sitting here pecking at my mobile device and trying not to cry. I just don't know how to keep enduring these losses. Worst of all, I can't go in again until 3/3 because she is away next Friday and Monday. So next scan will be at 6 weeks 5 days (unless I start to bleed first).
