Patient's question:
Medical Description: My menstrual period was delayed by five days this month. Usually, it would come three days early. On the fifth day, I took a pregnancy test, which showed a faint positive result. However, on the sixth day, I started bleeding—first red, then black. I went to the hospital for a check-up: the urine test was positive, but the ultrasound revealed nothing, not even a gestational sac. Additionally, my blood test showed an HCG level of 121.90 mIU/mL. In the past few days, I have been experiencing black, viscous discharge from my vagina, a heavy feeling in my lower back, and extreme fatigue. Could this be an ectopic pregnancy or a miscarriage? What should I do?Doctor's answer:
A false positive on an early pregnancy test is generally caused by a combined "imbalance" of physiological and psychological factors, which affects the function of the hypothalamus and pituitary gland, leading to this phenomenon. When a woman experiences symptoms of pregnancy, it is best to have an HCG test at the hospital rather than relying on the results of an early pregnancy test. Although early pregnancy tests claim to have a 99% accuracy rate, the actual accuracy of these tests varies greatly, ranging from 50% to 98%.If you have a high chance of being pregnant, use an early pregnancy test on first-morning urine and check the results after 15 minutes. If there is one red line, it means you are not pregnant. If there are two red lines of the same color depth, it means you are pregnant. If there is one dark and one light red line, it indicates a possible pregnancy, and you should test again after 2 days until you get either one red line or two red lines of the same color depth.
