So as of tomorrow I'll be 6 weeks and I'm going for my first OB appt and I was told I will receive an ultra sound to measure the baby and set a due date. I have had 4 miscarriages and I'm so deathly afraid they will go in and not see anything. I just want to see that sac and yolk if not the heart beat! I just wanna see something. I'm so nervous! What do you ladies think I will get to see at exactly 6 weeks?
