How can this be?

Shel
After two years of infertility I finally got my BFP. I was so excited!  Thought my dreams were coming true. Went to my RE at 6 weeks.  He saw nothing. Decided my dates must be wrong. I was willing to believe I ovulated late. Did hcg, and told me to come back for repeat labs and US in two days. Wonderful news!  There was a gestational sac and the hcg was rising appropriately. I was so relieved. I continued to take clear blue easy tests and watch my weeks rise. I had more and more symptoms every day. I envisioned my family coming together. I went back to RE at 7+1 to see my baby's heartbeat. I was so nervous!  The ultrasound quickly showed a much larger gestational sac!  But clearly it was empty.  There was nothing at all there. A blighted ovum measuring 6 weeks. I have never been more devastated. I am waiting on something to happen. My symptoms disappeared literally overnight. I am having cramping and hope this develops into bleeding soon. I don't know if I can wait weeks to have closure. But, I also feel like I can't make a decision to speed it along either. What if they were wrong?  What if my tilted uterus just obscured their view?  I know it didn't. I guess I'm just not ready to face it yet. My heart goes out to each of you on this page.  Miscarriage is so dark and lonely.
