It's still only 6weeks. They say 8 because they don't know the date you really got pregnant.
Well they measured my baby by ultra sound . And it was measured 8 weeks . That's the confusing part to me . I know they add two weeks due to lmp . And my Bf is really iffy about that he trusts me bt I know he has a doubt in his mind /:
No they say your 8 week's which means you conceived 6 weeks ago.
they count from the beginning of your last period. they pretty much add an extra 2 weeks on. so they say your 8 weeks, but really your fetus is only 4 weeks. they do this bcuz they dont when the baby was conceived, so by counting from the first day of your last period helps to make things more accurate for them. hope i helped! and congrats!.
