Is a Negative Pregnancy Test Result Indicative of Pregnancy or Not?

A negative pregnancy test result indicates that the early pregnancy test has found the test strip to be negative, and it is temporarily not possible to determine whether or not a pregnancy has occurred. Early pregnancy tests are used to determine pregnancy status through qualitative measurement of HCG in urine. Around five weeks of pregnancy, the HCG hormone levels in the blood and urine of pregnant women will increase to varying degrees, and the early pregnancy test will show a positive result. If the test result is negative at this time, it means that there is no pregnancy. If the pregnancy is too short and the test result shows negative, it cannot absolutely exclude the possibility of pregnancy, because the HCG in the urine may not have started to rise or the rise may not be obvious enough for the early pregnancy test to detect. In this case, it is necessary to observe menstrual conditions and recheck after a week's delay to see if there is a pregnancy. Alternatively, a blood test can be taken at the hospital ten days after sexual intercourse to measure blood HCG levels and further determine pregnancy status.

During a gynecological examination, the doctor may observe that the uterus has begun to enlarge, the cervix and lower uterine segment have softened, and the color of the vaginal mucosa has darkened. This type of examination performed on women two weeks after conception is nearly 100% accurate.

Urine testing is the most commonly used method to determine pregnancy. After conception, the hormone hCG (human chorionic gonadotropin) increases and is excreted through the urine. This is the principle behind early pregnancy tests and hospital testing. Its accuracy is over 90%, and it can detect pregnancy as early as two weeks after conception. If the test is performed after four weeks of gestation, the results will be more reliable. For home testing, it is recommended to use morning urine, which can increase accuracy.

Typically, an ultrasound examination is performed during early pregnancy to check for normal intrauterine pregnancy. During the fourth week of pregnancy, the signs of pregnancy may not be clearly visible on ultrasound.
