Best Answer

It takes 3 or 4 days after implantation for sufficient hormone to be produced, so wait until 14 days or so after sex to do a pregnancy test.

answer


Implantation bleeding can happen when the egg implants in the uterine wall. It is not something that happens in every case. You can have implantation bleeding and NOT be pregnant as well, because the blastocyte may have genetic abnormalities that do not permit growth, thus the egg dies.

a pregnancy test shows the best on the first day of your missed period. It rarely can give you a correct answer before that. SOme expensive tests promise a correct answer 1-3 days before the first missed day but I don't think it is very acurate.
