When to Take a Pregnancy Test

Pregnancy Test

When should you take a pregnancy test to see if you are pregnant.  It all depends on what kind of pregnancy test you plan to take.  Some pregnancy tests are more sensitive than others and a blood pregnancy test is more sensitive than a urine pregnancy test.

Blood Pregnancy Test

A blood test can be done a day or two after implantation.  You can have a qualitative pregnancy test or a quantitative pregnancy test.  The qualitative pregnancy test just says “yes, you are pregnant” or “no, you are not pregnant”.  The lab will take some blood from you and run the test, which is available after just a few minutes.

A quantitative pregnancy test will tell you and your doctor exactly how much HCG is in your system.  This is sometimes done if there is concern that you might be having a miscarriage. In a normal pregnancy, the HCG level doubles every 48-72 hours and, in an unhealthy pregnancy, the HCG level doesn’t rise as much, stays the same, or will go down.

Urine Pregnancy Test

Feel free to check earlier than that but be prepared to check the urine test again if the first test indicated that you weren’t pregnant but you still feel like you are.

Urine tests involve peeing on a stick or into a cup and uses the stick to wick up some of the urine into a test window. There can be a digital test that just says “yes” or “no”.  You can also use a test that asks you to compare the intensity of two lines—a reference line and the testing line.  If you are uncomfortable with the double line test, invest in a digital test that will give you a definitive answer.
