Worrying myself sick

Today I'm 5w2d and have an u/s appointment because of my history. I'm so worried. I have absolutely no symptoms except for a missed period. I did have labs done and they were doubling which eased my mind for a few days. With my first pregnancy (which ended in a late trimester loss) I had the typical symptoms- sore boobs and vicious morning sickness. I just hope and pray that everything will be ok...😔
