My husband and I began our Thursday really excited to see our baby at our first ultrasound only to see an empty yolk sac.  I had a transvaginal ultrasound.  We thought we were about 9 w so we should have definitely seen the baby.  The doctor explained that either we are a few weeks off (meaning I'm not as far along as we thought) or I will miscarry.  I have another ultrasound scheduled next week.  Anyone have this happen and the outcome was positive?  I'm so emotional right now!  I have had all the typical pregnancy symptoms and no spotting/bleeding.  I know when my last period was and know the week we conceived.  I have always been regular with my cycles.  My first positive pregnancy test was the week of June 13th.  Help!
