When Is Too Early for a Pregnancy Test?

How soon can you take a pregnancy test? You should wait to take a pregnancy test until the week after your missed period for the most accurate result. If you don't want to wait until you've missed your period, you should wait at least one to two weeks after you had sex.

How soon will a pregnancy test read positive?

It varies by test, but in short, the soonest a home pregnancy test can read positive is about four days before your first missed period, or about three and a half weeks after an egg is fertilized.

Can a pregnancy test be wrong if taken too early?

In most cases, home pregnancy tests can detect levels of hCG around 10 days after successful implantation of an egg (which doesn't happen immediately after sex). If you take the test too early, you might get a negative result (even if you are pregnant).
