HGC Levels

This is my first pregnancy and I had lab work done but they don’t check HGC levels? I had my first appointment last week, I was 6weeks and 1 day, and she said since I’m confirmed pregnant and I saw a heartbeat in the ultrasound, they don’t continue to check HGC levels. All she said was that my lab results are great. Is this normal? I really wanted to see my levels.
