Will a home pregnancy test work as early as week 4?

Many home pregnancy tests are effective after the first missed menstrual period. A missed period often coincides with the 4th week of pregnancy. Therefore a home pregnancy test might be possible towards the end of the 4th week.

During week 4 of pregnancy, you may first suspect that you are pregnant. You can take a pregnancy test this early, but some tests may not be accurate until week 5. If you do take a home pregnancy test, wait until till the end of the week to take it. These tests are also more accurate if you take them first thing in the morning, since that is when your urine is most concentrated. If you get a negative result but still suspect that you are pregnant, wait another week and then take another test.
