Prompt please, in 3 weeks from the date of conception the size of a fetus 8, 7 mm. But in all books write for this term the size to 2 times less. What does it mean?
And more, whether normally at such pregnancy to go to a toilet 1 in 3 days?

There is at me a suspicion that the size of an embryos which really on this term is confused is peer 0, 3 and diameter of a fetal egg which is peer 0, 8 see the Acceleration of a chair probably on early durations of gestation.
