How do you count pregnancy weeks after conception?

Has anyone heard of counting 9 full moons after your conception date to predict the birth of your baby? My aunt just told me this. I’m due January 22nd but I kept saying I think I’m going to have a Christmas baby! When I count the 9 full moons after my conception date, it says December 26th 😳

Did any of you ladie's obgyn schedule you for a pap smear early in your pregnancy? Is there really a need for this, or should I wait until after I have the baby?
