When can I take a pregnancy test. When my period is late .

It is recommended to take a pregnancy test when your period is late, as this is the most accurate time to detect a pregnancy. If you take a test before your period is due, you may get a false negative result. If your period is already late, it is best to take a pregnancy test first thing in the morning, as this is when your urine is most concentrated and will provide the most accurate result.
