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).
Beyond answering the question implantation bleeding or period, a pregnancy test will always be the best way to ease your mind. Be sure to take the test after your regular period should have been and not immediately after the bleeding. Even if it is implantation bleeding, the pregnancy test will probably still read negative as hCG levels in will be insufficient. On average it takes about 48 hours to get even a faint positive test.
