What does it mean if a pregnancy test does not show any result?

Inconclusive: This is rare when this happens but my suggestion is to try again this is happen very infrequently.

Need to redo: If you had sex since your last period and missed your period by 4-5 days, do a home pregnancy test. . If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD.
