How long periods get delay after taking ipill. took home pregnancy test but it resulted negative. does this mean i m pregnant and result is nt correct?

Tests are accurate: Today's home pregnancy tests are very accurate, but 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 if she did the first test too early, such as less than two weeks after conception.
