In brief: You

You can either take a home pregnancy test as long as it has been 5- 6 weeks since your last normal period (3-4 weeks since having unprotected sex), 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 or 3-4 weeks after conception. 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.
