So would i normal pregnancy test confirm am pregnant of a blood test if i have pcos?

Tests are accurate: Today's home urine pregnancy tests are very accurate and not affected by PCOS. However, if done too early, a negative result may be due to testing too soon. A correctly done urine test will give a reliable result 3 weeks after sex (when conception might have happened) or 1 week after missing a period. A woman can repeat the test later, if she did the first test too early.
