Question: How long should I wait between pregnancy tests?
Answer: Most pregnancy tests include instructions that encourage you to wait at least one week between a negative test and taking another pregnancy test. This is to allow time for your body to build up enough hCG to be detected in your urine.

You may choose to test sooner, knowing that hCG nearly doubles every 48 hours. This is not harmful to anything other than your wallet. Though you may continue to get a negative result until your body builds up enough hCG to turn the test positive, if you are pregnant.

You may also wish to consult with your midwife or doctor about having a blood pregnancy test drawn.

If you continue to get a negative pregnancy test after a week and you have still not started your period, it is wise to have a physical exam by your doctor or midwife to ensure that you are healthy.
