How long does it take after conception to become pregnant?

Why do you add 2 weeks to pregnancy?
If your period is regular and lasts 28 days, and if ovulation generally happens on day 14 of your cycle, then conception probably took place about two weeks after the LMP. For gestational age counting, these two weeks are added to a pregnancy as a simpler method than trying to track from ovulation or fertilization.
How many weeks pregnant are you at implantation?
