Month 1 by Yvonne :D

FETAL DEVELOPMENT

Month 1: Your first month of pregnancy your baby will accomplish many things, first and foremost, conception, fertilization, and implantation. After a woman ovulates, the egg is normally fertilized within 24-48 hours. The single fertilized cell begins to rapidly divide and at this point in time is called a zygote. Many amazing things happen at fertilization. Your baby's entire physical attributes are determined including gender, hair color, and eye color. Between days 7-10 from fertilization implantation usually occurs. Implantation should occur within the uterus if it does not this is considered an ectopic pregnancy. The amniotic sac, umbilical cord and yolk sac are already beginning to form. By the end of this month your baby is approximately 2mm long and beginning early stages of development.

Month 2: Your baby is now considered a fetus. Her heart, neural tube, arms and legs, liver and other major organs begin to form. By your 6th week, her heart will be beating and visible via ultrasound. The placenta also begins to form as well as the eyes, ears, mouth, and bones. In this month, your baby's fingers and toes will become present, however, they may still be webbed. Her brain and cranial nerves will also begin to form this month. Baby's sex organs begin to become visible. Your baby is approximately 1/2 inch - 3/4 inch long and weighs about 1-2 grams by the end of this month.

Month 3: If given an ultrasound now, you would be able to see your baby's arms and legs moving. Baby's heartbeat can be detected by doppler beginning in your third month. Development of the heart and all major organs is complete by the end of the third month. Baby's sex organs continue to develop, but it is still too difficult to differentiate gender. Baby's muscles in trunk, limbs, and head are developing. Baby's face is well formed and your baby looks like a baby. By the end of your third month, your baby is 3-4 inches long and weighs about 1 ounce.
