Hello,
Welcome to the ehealthforum and I am really glad to help you out.
Your concern is about the HCG and progesterone levels at 5 weeks gestation. According to the American Pregnancy Association, for HCG levels; anything from 18 - 7,340 mIU/ml is considered normal at 5 weeks and the progesterone levels can range from 9-47ng/ml in the first trimester. So your values are absolutely fine.
Further the levels of HCG should double every 48-72 hours and progesterone levels should increase with an average of 1-3ng/ml every couple days until they reach their peak for that trimester.
I sincerely hope that helps. Take care.
