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.
