HCG Beta test results

Heather • Married 11 years, Mommy to 2 angels, a 2 year old rainbow baby, and due 3/5/21!
After 7.5 years of trying, and one partial molar pregnancy last year, we got a BFP yesterday at 13 dpo! Went to get a beta done, and it was 57. Is that too low? I'm such a nervous nelly after the way my first pregnancy ended... I called the fertility clinic, but the medical staff wasn't available, so I'm waiting for a call back.
