The normal range for progesterone at two weeks of pregnancy is 63.6 to 95.4 nmol/L, while HCG values should be greater than 25 U/L as normal. Progesterone shows a rapid increase after a woman has successfully conceived. A progesterone test in the early stages of pregnancy can help to determine the health of the embryo’s attachment and early development, and can effectively determine the safety and reliability of the early stages of pregnancy. The normal range of progesterone is 63.6 to 95.4 nmol/L at two weeks of pregnancy. HCG is human chorionic gonadotropin. In early pregnancy, HCG is less variable, so a level greater than 25 U/L at two weeks’ gestation is generally considered normal. As the pregnancy cycle increases, the HCG value will show a doubling every other day. Regular hormone level checks can provide some indication of the health of the fetus and the mother.
