is it normal

Hey guys I had a miscarriage in February and pregnant again! I called my dr yesterday to confirm my pregnancy I was told that they don't do that anymore since at home tests are so legit these days. But I did get my apt scheduled for June 15th which puts me like 8 weeks and 5 days. I was just shocked they don't confirm before first ultrasound. I'm so nervous as I was told at my first ultrasound last time it looked like I was having a failed pregnancy and to come back in a week. Everything seems to be going well (I think) but I'm fearful of that happening again. How can I keep calm and reassured everything is okay?
