I just had an ultasound at 6 weeks myself just yesterday and they too said they didnt see anything yet. They said they see a sac but have not seen the fetus yet.I as well am freaking out but I keep telling myself that it is early and that due to the fact that I am feeling fine and it is early that I should not worry.I wish you and your husband the best and again I know what you are going through.
it's usual not to see ANYTHING till between 7 and 8 weeks. by that stage, you should see a heartbeat, sac and possibly a fetal pole.
probably easier said then done right :P
Your still pretty early.I bet if you went back in a week or two you would be able to see the fetus. thats why alot of drs don't want you to have a sonogram until your further along. just so your not stressed out. but also if your doctor didn't seem stressed then you have nothing to worry about
