First month of pregnancy: Changes and developments

The first month of conception is of the most crucial periods in the nine-month long journey. We help you know the changes you and your baby are going through

Most women sail through the first month of pregnancy without even realising that they are pregnant. However, for some, it can be as exciting as exhausting. A woman's body undergoes tremendous changes in the first month of pregnancy, which can make her life a roller coaster ride. Pregnancy not only alters the body of a woman but also affects the emotional well-being of a mother-to-be.

Some of the common changes that woman may encounter in her first month are:

  • Sore breasts
  • Lethargy
  • Cravings and aversions to certain food
  • Feeling extremely emotional
  • Nausea
  • Urge to urinate frequently
  • Constipation
  • Dizziness



What is happening with your baby

Besides understanding the changes that your body is going through in the first month of pregnancy, it is also essential to understand how the baby is shaping up inside your womb.

In the early weeks, the sperm's nucleus commingles with the egg and your baby's gender is determined. Sperm carrying a Y chromosome generally results in a baby boy, while the one carrying an X chromosome in a bouncing baby girl.

During weeks one and two, the fertilised egg, otherwise known as a zygote, divides into multiple cells and starts burrowing into the rich lining of the uterus. Your precious baby is simply a ball of cells that transforms at this point into a blastocyst. The blastocyst consists of an inner cell mass that eventually transforms into the embryo, another cavity that becomes the amniotic sac, and an outer cell body that will become the placenta.

By the time you are three weeks pregnant, your baby consists of a ball of cells that can fit into the head of a needle. Till 4 weeks, the amniotic cavity is complete and the placenta starts taking shape. Your baby's organs also start developing.

By the end of the first month of your pregnancy, your baby is around 6-7mm long, approximately the size of a rice grain.
