Still doesn't feel real💗

I still haven't scheduled my first appointment. According the app and from my lmp I should be 5 weeks exactly today. I might wait a week or 2 before even scheduling the first appointment just to make sure it sticks. which I'm sure it will because I've only had one miscarriage about 9 years ago. This will be baby number 4! Is it bad to wait to schedule the first appointment? I've always called the doctor right away but when you're this early I feel not a lot happens at the appointment.
