Thanks, the nurse just called me; they sent out the US for a second opinion, and are confident it was just a cyst- however, I'm measuring at less than 5 weeks- just a sac and yolk sac apparently no fetal pole. My LMP was Oct. 4th, I have 34ish day cycles normally so I do ovulate later than normal. I got my positive test on Halloween (Oct, 31),it was VERY faint, so unless I was 7 dpo I should be measuring bigger? Maybe someone can help me figure out my dates better? I'm terrified now that baby isn't progressing and I should be measuring bigger than this. :/ I have a repeat US in 2 weeks to check growth. They taking blood tomorrow (friday) to check hcg levels, and again on Monday as labs are closed saturday and sunday. To see how they're rising. So it's better than hearing I have an ectopic, but still not what I wanted to hear.
