3 Weeks Pregnant

Third week is the time when the sperm comes into contact with the egg inside the fallopian tube. When the sperm fertilizes the egg, an embryo is formed. This is the beginning of the pregnancy. This is also the time when the gender of the baby is determined. The man’s chromosomes are responsible for the baby’s gender. Some women may experience spotting during this time. The spotting takes place because of the movement of the fertilized egg into the uterus. This spotting is referred to as ‘implantation bleeding’. During this time, the woman’s body releases an immunosuppressant protein called ‘Early Pregnancy Factor’ or EPF. The EPF prevents the woman’s body from treating the embryo as an invader.

After the ovulation has occurred, women are advised to visit their gynecologist to confirm their pregnancy. Doctors usually prescribe women folic acid tablets during this time. Iron tables are also administered. Women may experience bouts of nausea during this time. Acidity too, is a common symptom.

The baby also registers growth during the third week. It is housed inside the uterine walls. At this stage, the baby is about 0.2-0.5mm in size, with its head measuring about 0.006in in size. Despite its small size, it is visible to the naked eye. It starts to develop its head, spinal cord, and gastrointestinal tract during this time.
