5 weeks 2 days

So I'm high risk, and my last pregnancy was so traumatizing no one ever thought I'd want another. I just found out I'm pregnant again (planned) and we went for our first appointment today. Baby is 5 weeks 2 days. We know it's early but I only saw the sack and a small yolk sac as well. Doctor told us to come back in two weeks to get a good look at baby and to start on my prenatal care (tests and so on) does this sound about right? Please tell me I'm panicking for no reason and that the baby will be fine come my next appointment.
