Taking progesterone tablets will not affect the early pregnancy test, progesterone tablets are a progesterone-based medication. Early pregnancy test paper is to detect whether there is chorionic gonadotropin in a woman’s body, and progesterone has no effect on HCG. So under normal circumstances taking progesterone tablets, you can still test the early pregnancy test paper. Factors affecting the early pregnancy test paper are as follows: 1, the time of intercourse, because HCG hormone levels are secreted by the trophoblast cells of the embryo, if the embryo is relatively small secretion of hormones is relatively small, only 14 days after intercourse can be detected in the women’s urine, if the test is too early, there is the possibility of false negatives. 2, the detection of the time of the urine has a relationship with the time of the test if the embryo is too small to test the women’s body in the morning of the first time If the embryo is too small, the first urine test in the morning will be more accurate.
