As far as conception no one knows but the count goes from lmp (last menst period) so for example: if you had your last period on june 20th and you found you are pregnant after testing on july 16th then your conception count will be from june 20th, even though it could have been june 25th who knows.it's like math rounding the figure. And so the fetus tend to have heart beat sometime in their 6th weeks or 25-30days.the fetus size at that point could be as big as rice grain to a small raisin.hope i answered your question
