Fetal development - month 1. First trimester. At the end of four weeks: Baby is 1/4 inch long. Heart, digestive system, backbone and spinal cord begin to form. Placenta (sometimes called afterbirth) begins to develop. The single fertilized egg is now 10,000 times larger than it was at conception.
The first month of life was a period of rapid growth. Your baby will continue to grow at a similar rate, gaining about 1 to 1Â½ inches (2.5 to 3.8 centimeters) in length this month and about 2 more pounds (907 grams) in weight. These are just averages â your baby may grow somewhat faster or slower, and is likely to have a growth spurt.
