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).
Spotting may be an implantation bleed so the embryo will not yet be producing any hormone to give a positive test. Leave it another week to take a test.   No, there is no â¦ t enough HCG to detect at such an early stage (assuming one week since fusion). Unless you have been sexually active and unprotected before that period and are not on the pill.
