If the menopause is less than one month old, then it is clinically difficult to detect pregnancy even if it is. It is recommended that if the test is done by blood HCG, it is best to go to the hospital at 31 or 32 days of menopause to have blood HCG drawn and checked. If the blood HCG is greater than 10 mIU/mL, it indicates pregnancy. If you are testing for pregnancy by urine, it is best to use morning urine after 35 days of menopause. When testing with morning urine, it is especially important not to drink too much water 2 hours before collecting the urine to avoid diluting the urine and causing a false negative result in clinical practice. If two red lines of the same color appear after the test, it indicates pregnancy, and if there is only one red line, it indicates no pregnancy.
