Just a quick update, becasue it is way past my bedtime. The scan showed empty uterus, the doctor says that since nothing is showing, I am not in pain, and 680 is low for even ectopic 7 week pregnancy, it was most probably just early miscarriage. I think he is right. Weird, I also think it is over now, bleeding stopped today. At least I can put this behind me and get ready for TTC again. I hope that the hcg will clear up fast now.
