I had an FET. My two weeks blood test was positive with hcg of 3146 miu/ml and 218nmol/l progesterone.

Two days after I repeaters this test and hcg had risen to 4845 miy/ml but progesterone dropped substantially to 48.8 nm/l.
Is this a cause for concerned. I am really stressing about the progesterone levels even though I am taken supplements.
