Am i pregnant? Online pregnancy test is positive

Dear Ask The Doctor: I think i might be pregnant. i'm having all the symptoms. every online pregnancy test i've taken has come back positive. i don't know what to think.

Dear Regan: Pregnancy is diagnosed by detecting the presence of a hormone, HCG, which is produced in pregnancy. Home pregnancy tests are highly accurate if used correctly and at the right time. The test is best done after 1 week of a missed period. If you are concerned about pregnancy, I suggest you visit your doctor for a simple blood test which is more accurate that a home pregnancy test.
