A negative urine test means that a woman has a negative urine pregnancy test, which only means that the HCG hormone in the urine is not elevated and cannot completely and absolutely rule out pregnancy. Some women may have been tested too early and the HCG hormone in the urine has not yet risen, hence the false negative phenomenon. The urine test should be done more than 16 days after the last intercourse to be more accurate, and if necessary, the blood HCG can be checked directly to determine. If the blood HCG test is also negative, the woman is not pregnant. If the blood HCG is elevated, it means that the woman is pregnant, but the period of menopause is relatively short, so you can wait for half a month for a follow-up ultrasound to confirm whether the pregnancy is intrauterine or ectopic.
