Week 3 of Pregnancy


You may not feel that you're pregnant yet, but your baby has already started growing inside you. The fertilised egg divides into two cells, then four, and continues to divide as it travels down the fallopian tube towards the uterus. By the time it gets to the uterus, this group of cells looks like a tin
y ball called morula. Once it has implanted into the uterine lining, it is called blastocyst and measures 0.1- 0.2 mm in diameter. Implantation happens about a week after fertilization with a range of 6-12 days. The implantation in the uterus creates an essential connection with the mother’s body that will provide the developing embryo with nutrients and will remove wastes.
Occasionally, when the fertilized egg implants itself into the uterine wall, women may experience a small amount of spotting. It does not usually look like a regular period but is scanty and usually a pinkish or brownish discharge.



Your body


You may still not be aware of the pregnancy but many great changes are happening inside your body. You have not yet gained any weight, but you need to be prepared to gain some weight during pregnancy. A healthy amount of weight gain is crucial for the well being of both mother and the growing baby. You can control your weight gain by eating healthy and nutritious meals and snacks. Refer to our section on diet during pregnancy nutrition to learn more.

This is also a time to begin your pregnancy exercise routine if you were not exercising earlier. Women who follow a healthy exercise routine during pregnancy can avoid many of the common discomforts of pregnancy. Start with gentle strengthening activities like prenatal yoga, brisk walking, swimming, or mild aerobic exercise.  Refer to our section on pregnancy fitness to learn more about the types of exercise that are safe during pregnancy.


Remember

Before you begin your exercise routine, it is better that you talk to your doctor. A sudden increase in activity can be a problem for you and your baby. If you have been pretty active till now, you will need to cut back your level of exercise.
