weeks

I'm 6w3d and for some reason don't nobody believe me when I say that I'm actually only a little over 4 weeks ( without the two weeks added ) but since the doctor have to go by my LMP they have to add two weeks on which will make me 6w3d even tho I know I ovulated on the 12th of September but they still have to go by LMP which add two weeks on meaning the first two weeks you not even pregnant yet
