DE IVF #1 - 1st Ultrasound not so good...

We had our first ultrasound yesterday and I'm very sad to say that I don't think it looks very good. Yesterday we were 6 weeks 2 days and the ultrasound indicated that we were only about 5 weeks, the gestational sac measuring 6.4mm with no yolk sac or fetal pole. I'm utterly devastated. Nothing seems to come easy to us.

Though, I suppose there could be some hope, the doctor said that sometimes it is difficult to interpret the results given because results of an ultrasound this early depends on the equipment and the technician preforming the ultrasound.  He thinks it would be best to do another ultrasound in approximately 10 day. In the between time I have asked to do another HCG test just to keep my mind at ease, hopefully. I do however understand that at this point the numbers don't continue to double but to know that there going up would mean the world to me.

I'll up date more when I find out when my tests will be... and the waiting continues. :(

Has anyone had something similar happen to them and it's turn out for the positive?
