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).
Implantation bleeding does not occur with every woman. Usually only about 30% of women will experience implantation bleeding. You will usually see implantation bleeding 4 to 7 days before your period is due if you are one of the 30%.ell if you had implantation bleeding, you usually will be able to test in about 4 or 5 days after that. If you have taken a pregnancy test already and it is negative, and then you take another one that is positive, your conception date would be about two weeks ago.
