Scan did not go so well.

According to my lmp i should be 7w6d but my scan 2 weeks ago showed a sac measuring 5w1d (instead of 5w6d) so i was hoping to see something in there, at least 6-7ish weeks. Well the sac is pretty much empty. There was some diminutive spot, not resembling a yolk sac or anything so we dont know what it is. The dr said she doesnt want to do a d+c yet, that i should come back in a week to see if there is any growth. I've been there, done that. I'm completely discouraged, disappointed and mad. I can't believe i have to deal with so much.
