If you take a pregnancy test before implantation occurs, the test will tell you that youâre not pregnant (since the production of the hCG hormone has not started, this hormone will not be in your system, and the test will not detect it).
Pregnancy tests (both home tests and blood pregnancy tests ones) look for the presence of hCG to confirm a pregnancy. Implantation must occur to for this hormone to be produced. If implantation has not taken place, a pregnancy test cannot detect hCG and will give you a negative result. So, implantation has to occur before a pregnancy can be recognized with a pregnancy test.
