Getting to the 8 week mark

The app says I’m 4 weeks pregnant. I called my doctor and they set an appointment for when I’m 8weeks. This is super hard for me. I almost want to test everyday until I go to the doctor but my husband says it’s wasting money. I’ve seen so many things about getting to the 12th week before your chances of miscarry go down. Any tips for this? I want to be stress free for the baby 😞😞
