Answer:Most home pregnancy tests should be used seven to 14 days after your last missed period.

If you try to test too early, the hormone that these tests detect—human chorionic gonadotropin (HCG)—may not have accumulated in your urine. This will result in a false negative result.

Be sure to read all directions carefully, and follow instructions to the letter.
