We have a yolk sac!

I had my first u/s yesterday (5w3d) and we saw the gestational sac with a yolk sac. We didn't see a fetal pole, but the u/s tech, Mary, said she didn't expect to see one that early. The gestational sac measured exactly 5w3d, so she said everything was looking good. My next u/s is scheduled for two weeks and by that time, we should see a heartbeat. I was really hoping to at least see a fetal pole, but my chances were only 50/50.....Hopefully the next u/s we'll see more! The good news is that I'm still pregnant (with one baby) and everything looks good for now. Please keep prayers and good thoughts coming our way....I'm still a nervous wreck!
