First ultrasound at 5wks 3 days??

I called for an appointment when I found out I was pregnant on Monday 12/11. I use Glow to track my periods so I know my LMP was 11/13. I told the woman at the Dr. office my LMP and she scheduled me for tomorrow 12/21.

I’m already terrified of not seeing a heartbeat because I’m so excited to even be pregnant and therefore fearful something will go wrong. Everything feels good so far physically. Sore breasts.

Is it odd that she scheduled me so early on??
