If you can’t detect pregnancy symptoms, you need to wake up the next morning and urinate for the first time to check the urine pregnancy test again. If the urine pregnancy test is still negative, in this case it is recommended to go to the hospital as soon as possible to check the blood HCG value. If the blood HCG value does not rise, then there is indeed no pregnancy. If the blood HCG value rises, it suggests pregnancy. Urine pregnancy test results are not accurate enough and there is a possibility of false negatives. So for those who have pregnancy symptoms and can’t detect pregnancy, basically you can take a blood test to check the blood HCG value to further determine whether there is a possibility of pregnancy.
