This can cause a false result on a pregnancy test. Also, if a woman has recently given birth the hCG hormone typically remains in her body until 3-4 weeks after giving birth. So the only way to confirm if you are actually pregnant after having received a positive test result on a pregnancy test is through ultrasound.

A negative pregnancy test result means the test hasn't detected hCG in your urine. If your period is very late, or you've skipped your period, and you get a negative result, you are unlikely to be pregnant.

Ignore any changes to your result after this time.
