Blood test back - should I worry?

Raina • Wife • Baby #2 due 7/16/19 • Lost our daughter, June Carter Z, to SIDS 6/7/18 • 21 years old • Chronically ill with POTS

My HCG was 30 in my blood test, I was supposed to be exactly 4 weeks.

My doctor wants to retest my blood tomorrow but I won’t get results till Monday - should I worry with this level of HCG hormone?
