Patient: description of the condition (onset time, main symptoms, hospitalization, etc.): Before the treatment in the General Hospital, endocrine problems adjusted for two months, normal after the doctor said that you can promote ovulation. I May 29 to menstruation, 6.2 to eat Furey 5 days to promote ovulation, to the 12th test found that the follicle did not grow, so four injections to promote ovulation, to 6.16 to check the follicle has been quite large, the doctor suggested that the 16th and 17th can be co-habitation, 6.18 and go to the test found that the follicle is more wrinkled, the doctor said that it is estimated to be in the ovulation, so they gave me three boxes of luteinizing body copper to eat, a total of 15 days to eat. I would like to know that after 15 days of taking the copper luteinizing body, on the 2nd of July, I used the morning pregnancy test paper to measure two lines, but one of them was relatively light, I would like to know whether I am pregnant, and does the test have any effect after taking the medication? Doctor：I think you are pregnant, check again in 1 week. The metabolites of progesterone excreted in urine are pregnanediol and its glucuronide conjugate, which are different from endogenous progesterone excreted in urine as pregnanediol. Therefore, endogenous progesterone production can still be measured to determine pregnancy based on the amount of pregnanediol excreted in the urine (early pregnancy test strips). This is misunderstood by many physicians.
