During human gestation, rudiments of all organs develop:
while the embryo is in the oviduct.
in the second trimester.
in the third trimester.
during the blastocyst stage.
in the first trimester.

While the normal human gestational period lasts for approximately nine months, the rudiments of all major organs arise during a relatively short period comprised (approximately) between the fourth and eight weeks of development.

Note that the embryo spends only the first 5-7 days in the oviduct, and begins implantation as a blastocyst with no organ rudiments per se.
