Hello, I just finished my first IVF cycle , we were estatic that on our fist try we became pregnant.... We thought everything was going well until I went for my US........

Now I sit here in a trance... Let me try to explain .. My Retrievel was done March 30th ,2011. Three days later my transfer, I went for my pregnancy test two weeks after, came back with a positive results, April 20th went in for blood test my HCG level came back at1600 , which I was told were great by the NP, she then said I would need to come back on my sixth week mark for a US, which I did on May 12...... Then everything came crashing down... My Doctor took one look at the image and got her calendar out and turned and said to me ..."Your baby is not growing , it stopped growing at 6 weeks..............I just sat there dumbfounded ,not understanding the words out of her mouth, when I could finally speak, in a voice not my own ,I meekly said but I am six weeks...."NO" she said your 8 weeks!! HUH???...your LMP was 8 weeks ago..... she proceeded to give me choices: 1 come back in a week do another US, 2 let mother nature run it's course, 3: have a DC.... I chose number 1... Now I sit here in misery...not knowing, hoping , praying....

Still very confused about the dates.......Has anyone gone thru this???
