Firstly, implantation bleeding is rare, and if you did get it...is only likely to last for around a day and be very light. Also....taking the test a week after having sex was WAY too early. Conception would have just been taking place at that point (if it indeed was). You would need to wait until your next period is due to take a test, if it's late that is. When was your last period, and when is your next expected one?
