Week 2 of pregnancy


During the second week of pregnancy your estrogen will increase, giving a signal to the uterus of a pregnancy. The uterus begins to form the “shell” where the egg is implanted, while the placenta that will nourish your baby is beginning to grow.

Your blood volume increases by 50%, to face the oxygen demand of the fetus growing inside you. Inside your body, you are creating a world safe for your baby to develop, protected from the outside.

The sharp pains in the sides of your abdomen are common symptoms during this period. Normally this is an indicator of ovulation, along with the sensitivity of the breasts.


This week your baby was conceived. The fertilized egg undergoes a process of division as you lower the uterus through the fallopian tubes. The cell is divided into two in the first 24 hours, and the fourth day is a mass made up of more than one hundred cells. The egg continues to divide as it is dragged through the fallopian tube toward the uterus, where it will take the name of morula.

At the end of this week the sex of your baby is determined. Biologically it is man who defines it, since it is the sperm which has in its genes X chromosomes (female) or Y (male), the only mother donates her eggs on the X chromosome. If the father gives an X chromosome (XX) will be a girl, if the sperm has a Y chromosome (XY), will be a boy.

After 2 weeks of pregnancy develops what is called an embryo, which is basically a head, a trunk and a curly tail. In the first weeks of pregnancy the embryo begins to develop the foundations of the organs, traits and nervous system.

During this week there are two small eye sockets, while training their ears and their eyes come at an early stage. In addition, it becomes hollow bone, muscles, kidneys, lungs, intestines and digestive system. It also begins to develop the neural tube, a tube skinned and bare bones will become the brain, spinal cord, nervous system and spine of your baby.2 pregnancy weeks 2 pregnancy weeks


If you smoke, is primordial to terminate this habit immediately, because this could result in poor fetal growth, while increasing the risks of miscarriage, or placenta previa (a condition where the placenta, or part thereof, is located in the bottom of the uterus, blocking the cervix).

Another point to keep in mind as you begin this process is to know your family medical history, since most of the complications in pregnancy and childbirth can be identified at the first visit to your doctor.
