hi, my last period was 05/15/2013, I had an ultra sound yesterday due to virginal bleeding, calculating from the 1st day of my last period I was 6.6wks gone, but the ultrasound showed a gestational sac of about 0.8cm, no yolk, no fetal pole, hcg showed 4590, could this be normal or is somethg wrong? bcos I expected to see somethg in there or even a heart beat at 6.6wks, even tho' I was told to repeat the blood work after 2days to be sure its raising, I am still worried bcos I had a miscarriage few months ago about the same time, ill go for anoda blood work tomorrow... someone should pls help put my mind at rest... thank u
