False negatives are much, much more common than
false positives. HPT
test for the
pregnancy hormone HCG. In order for you to get a
positive on a hpt you need to have that pregnancy hormone present in your body. With that being said, you can be very very early in your pregnancy, or you may have had an early miscarriage.
I agree with the other ladies though. If I were you I would try a different test. (Try first response early detection) Or you can go to your local clinic and get a blood test.
