1. Try to use the first urine in the morning for testing, because the hormone levels at this time are the easiest to detect. If it doesn't work, make sure that the urine is in the bladder for at least four hours before being used for testing.
2. Don't drink too much water in order to increase urine, because this will dilute the level of hormones.
3. Read the instructions carefully before starting the test, and follow each step accurately.
4. Some drugs may affect the test results, so be sure to read the label instructions carefully.
In addition, if it is an ectopic pregnancy, the HCG level may be very low and cannot be detected by the pregnancy test stick. To confirm the test results, you must see a doctor.
