high progesterone but hcg didn’t double

i got my positive at 11dpo on sunday and had blood drawn monday at 2:30pm and again wednesday at 10:30am. i miscarried at the end of december and immediately got pregnant again, so they want to check everything of course. monday hcg was 150 and wednesday hcg 180, but progesterone is great. i went again today (friday) and i’m so nervous. can anyone share their stories or information? i don’t want to believe we’ll lose another baby.
