I am one day away from ny period . Did blood test for hcg. The first was taken on 20th September afternoon around 3.15 pm, the value was 41(non fasting) and the second one was taken on 22and September around 9.15 am (fasting), the value was 66.Is it normal? The nurse told me yesterday that I should expect 80 or more for healthy and safe pregnancy.
