Hormone levels

Does anybody know what is considered good progesterone levels for the first trimester ? Six months ago I had a m/c when I had two rounds of blood work the hcg was great and low prog. This time around from four to five weeks my hcg went from 500 to over 1000 and prog 14.8 to 16. Dr said its fine but I'm still nervous giving my history! Thoughts or advice ? Am I overreacting ?
