Progesterone does not affect the result of the early pregnancy test. Progesterone belongs to the progesterone class of drugs, so women take progesterone to supplement the progesterone content in the body, which may affect the progesterone, but because progesterone is absorbed into the body through oral intake, the effect of progesterone testing through blood sampling is not particularly great. HCG is also known as human chorionic gonadotropin, which is a different hormone from progesterone, and is secreted by the placenta after pregnancy. Taking progesterone will only affect the amount of progesterone and the level of progesterone, not the concentration of HCG, so it will not affect the result of the early pregnancy test.
