HCG and progesterone

Megan • Adult/Pediatric Trauma RN., BSN. Family Nurse Practitioner student. Mother to an angel. Baby girl born July 3, 2017.
I'm 4w5d and my HCG: 403 and progesterone: 8.6
I have to have repeat blood work on Thursday morning, but I'm already anticipating the worst. 
Has anyone had a progesterone level be this low that sustained a viable pregnancy after supplements were added?
