Taking progesterone will not affect the results of early pregnancy test. Taking progesterone is mainly to supplement progesterone, mainly suitable for patients with luteal insufficiency. Luteal insufficiency may lead to miscarriage or habitual abortion, so it is generally recommended that patients take progesterone after ovulation, mainly to replenish the luteal function, in order to maintain the development of the embryo. The test of early pregnancy test paper is mainly to detect the level of blood chorionic gonadotropin, also known as HCG, in the urine of the patient, so taking progesterone will not affect the results of early pregnancy test paper. If the patient is taking progesterone because of luteal insufficiency, it is recommended that the patient take it until the results of the pregnancy test come back. If the pregnancy test result does not show a pregnancy, the medication can be stopped and menstruation will occur within a week after the medication is taken.
