At fertilization there is no embryo. The fertilized egg doesn't instantly just pop into a little baby. The fertilized egg, which is still an egg, attaches itself into the wall of the uterus (which is normally shed during menstruation), this process is called implantation. You may experience 1-3 days of light bleeding at this time. After implantation, the cells in the egg divide and divide and divide etc. Then the divided cells begin to merge back together which is the beginning of the formation of the fetus at week 4. So there is quite a huge difference from fertilization until week four.
What else can I help you with?

What is the function of the fertilization envelope?
The fertilization envelope acts as a barrier that prevents polyspermy, which is when an egg is fertilized by more than one sperm. It also helps in the activation of the egg and plays a role in the early developmental processes of the embryo.
What if your placenta sac is larger than the embryo?
it is impossible to be bigger than the embryo since it grew with it so it has to be smaller, if the placenta was bigger than the embryo, the baby would probably die, if its lucky and survives, it would have a big belly button ,the guy who answered this question was me, but i forgot to sign in...........................
At what stage does an embryo become larger than the zygote?
After cleavage finishes, the cell cycle continues as normal - cell division slows, yet cells grow in size instead of just continually dividing. This is when gastrulation begins (the in-folding of the hollow blastula into multiple germ layers forming the ectoderm, mesoderm, and endoderm).
Does oogamy always involve fertilization from gametes of different sizes?
Yes, oogamy is a form of sexual reproduction where the female gamete is much larger than the male gamete.
