At the miraculous moment of fertilization – when the egg of a woman and the sperm of a man unite, a new human life begins. From this moment on, it will take approximately nine months for the baby to develop and be ready to be born.
Only 5 % of the babies are born exactly on their due dates. The long awaited day is near and soon you will be holding your baby in your arms. Your baby has lost his lanugo hair although you may still find some at his back and on his forehead.
Your baby’s eyes will be blue at birth but this can change in the weeks to come. Some babies arrive a bit earlier, others a bit later, but they do arrive! So, much luck and happiness with the new baby in your life!
The average baby will be about 7.5 pounds (3.4 kilograms) and 20 inches long at birth. The placenta will weigh about one eighth the size of the baby and the umbilical cord will be about the same length as the baby.
Embryo, 3 to 4 weeks. A 6mm embryo is identified which shows a possible heart bulge on the anterior surface. No limb bud is seen. (Photos: Lunar Caustic)
An embryo from an ectopic pregnancy which is approximately 3 to 4 weeks estimated gestational age from conception. It was 0.5 cm long. See larger view for detail. (Photos: Lunar Caustic)
Embryo at 4 to 5 weeks. This is an embryo at approximately 4 to 5 weeks from conception. This was an ectopic pregnancy in a fallopian tube. (Photos: Lunar Caustic)
Embryo, 6- 7 weeks. Approximately 6 weeks estimated gestational age from conception, 8 weeks from LMP. Shot with 105 mm Micro-NIKKOR lens with 2 off camera SB-800's. Specimen is submerged in alcohol. (Photos: Lunar Caustic)
Embryo received with membranes intact. 1.6cm. EGA approximately 6-7 weeks from conception.(Photos: Lunar Caustic)
This is an approximately 6-7 week estimated gestational age 19mm embryo from conception, 8-9 weeks from LMP. Features include finger rays and cerebral hemispheres. (Photos: Lunar Caustic)

Ectopic pregnancy: Fallopian tube with extruded placenta and embryo still within amniotic sac. The embryo is approximately 6-7 weeks EGA from conception. (Photos: Lunar Caustic)
Embryo at 7 - 8 Weeks from conception. (Photos: Lunar Caustic)
Embryo at approximately 8-10 weeks EGA from conception. This embryo still has its amniotic sac intact. The most notable finding is the extraembryonic coelom which contains loops of small bowel. (Photos: Lunar Caustic)
The most notable finding of this embryo is the loops of small intestine in an extraembryonic coelom. At 10 weeks these will return to the abdominal cavity. (Photos: Lunar Caustic)
Embryo week 9-10. Notable in the this fetus is an extraembryonic coelom in the umbilical cord. Loops of intestine are seen as a bulge of orange material in the cord near it's attachment to the abdominal wall. These loops will withdraw at arould week 11. If these do not return, the condition is called an omphalocele. (Photos: Lunar Caustic)
Fetus 10 - 12 weeks. CR 3.6cm. For perspective the foot length is 0.6 cm which is about the same length of the embryo in the following picture on the photostream at 3 - 4 weeks developement. You will need to view on black to get a feeling for the detail. Use the magnifying glass button above the photo. (Photos: Lunar Caustic)
