About implantation..: Only after a positive preg. test can tell a woman that PRIOR spotting was actually implantation spotting. It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result about 3 weeks after sex (3 weeks after when conception might have occurred) or 1 week after missing a period.

Implantation bleed: Implantation bleeding is much more common on the internet than in real life. It occurs rarely and exclusively in someone who is pregnant. The only way to know if someone had implantation bleeding or just irregular menstrual bleeding is to wait and see if you are pregnant. If your test is positive then this was implantation bleeding. If it is negative then it is just irregular menstrual bleeding.
