Month 2: Critical time for major body organs

  
This month is especially critical in the development of your baby. Any disturbance from drugs, viruses, or environmental factors such as pesticides may cause birth defects.

Your baby's development is very rapid during the second month. By the end of the second month, all of your baby's major body organs and body systems, including the brain, lungs, liver, and stomach, have begun to develop. The first bone cells appear during this time. Eyelids form and grow but remain sealed shut. The inner ear is forming. Ankles, toes, wrists, fingers, and sexual organs are developing. At the end of the second month of pregnancy, your baby looks like a tiny human infant. If it is a boy, the penis will begin to form. If it is a girl, the vagina begins to form. From the end of the second month the embryo is called a fetus.

Mother
By the end of the second month, you may begin to feel pregnant. In response to the increase in estrogen and progesterone levels, the milk ducts in the breasts increase. As a result, the breasts may swell and become tender. You might be experiencing morning sickness or nausea during the day. Don't be surprised if you undergo some raging mood swings as well. Fatigue is also an issue throughout the first trimester. You may be just a bit more tired than usual, or you may be so exhausted that four-hour naps every afternoon are the rule. Those constant trips to the loo continue, no doubt natures way of training you to wake up several times during the night in preparation for your baby's feeding schedule.

Baby
Your unborn baby has now graduated to being called a fetus. His or her internal organs are already in place and ready for further development. If you have an ultrasound scan, you may see your baby wiggling and waving like mad, but you won't feel anything yet. An eight-week-old fetus already has distinct facial features. The fetus is a less than 1 inch long (2 centimeters) and still weighs less than a tenth of an ounce (less than 2 grams).
