As . As doctors, anytime a fertile, sexually active woman has an abnormally light or missed period, the first thing we do is rule out pregnancy. You can either take another home pregnancy test as long as it has been 5- 6 weeks since your last normal period, or you can go see your doctor and they can test you. A home pregnancy test is 97% accurate if taken a week or more after the missed period, so another negative test would help confirm that you are not pregnant. A blood test can tell if you are pregnant as soon as 7 days after conception and a doctor's urine pregnancy test can tell if you are pregnant around when you next period should come.
