Anyone know about HCG levels?

Morning ladies! I was confirmed pregnant by my family dr on Friday ❤️❤️ hubby and I couldn't be happier, this is #1 and we were TTC for 10 months. She did a urine test to confirm, and also took blood. My levels came back at 82. This seems really low, any insight? I go back in a few days to see if they've doubled as they should. Any insight on HCG would be helpful! Thanks!
