1.When can I use early pregnancy test strips for pregnancy test? You can usually start testing 2 days before your menstrual period is expected, or as early as 4-5 days before your menstrual period is expected. 2.When is the best time to use urine for testing? Urine from any time of the day can be used for testing, but it is best to use the urine from the first discharge in the morning, when the concentration of HCG in the urine is higher and more sensitive for the detection of new pregnancy. 3.Does taking medication affect the results? General medication (such as cold medicine, antibiotics, painkillers, etc.) does not affect the accuracy of the test, but if you take injections or pregnancy medication, the results may be affected. 4.Does a positive test result necessarily mean that I am pregnant? Under normal circumstances, a positive result indicates that the test taker is pregnant. However, a positive result may occur in the following cases: ectopic pregnancy, inevitable miscarriage and other abnormal pregnancies; uterine fibroids, gravida or menopausal patients may have a positive result due to high HCG content in the urine. 5.If the test result is negative, what should I do? It means you may not be pregnant, if you still do not see your period within a week, you should test again, if the second test is still negative, please exclude gynecological diseases.
