1st ultraound at 5 wks 2 days

Today we found out I have one little bean in my uterus....it was very hard to see (high in my uterus). Doc measured gest sac bet 5-6mm and yolk sac bet 2-3mm. It was blurry looking, not as much of a clear sac like my daughters or my last pregnancy. Doctor just said it's early and the telling sign will be on Nov 19th when we want to see a heartbeat.
My BETA went up from 333 to 1415 in a week....which is the 66% every 2-3 days they want to see, but of course not as satifying for me.... with my daughter they went from 368-3000 in a week... I know it's bad to compare, but she is a healthy little one, so I do.
So, I don't know what to make of this.... hoping God is with us, and this pregnancy keeps progressing and turns into a healthy baby!
