Pregnancy Week 3

Mother:

1. You have ovulated and have now been exposed to sperm!
2. When the egg implants some women have a tiny bit of spotting called implantation bleeding, where the egg burrows into the uterine lining, shedding a bit.
3. Your body also releases an immunosuppressant protein called Early Pregnancy Factor (EPF) to prevent your body from seeing the baby as an invader.
4. Fertilization occurs about the beginning of week 3 of pregnancy.
5. The fertilized egg of a divides until a solid ball of cells is formed.
6. Then, it travels down the fallopian tube into the uterus, during a seven to ten day trip, where it eventually implants into the uterine lining and continues to grow and develop.
7. You might experience some spotting or light bleeding at the time of implantation.

Baby:-

Cell division begins immediately and continues throughout this journey. Once in the uterus, it is generally about 72 hours before implantation occurs. Once it has implanted your baby is called a blastocyst and is about 0.1-0.2 mm in diameter. At 3 weeks pregnant, your baby is too small to detect with the naked eye, even though he is growing remarkable fast. By about this week, your baby consists of a ball of cells that can fit into the head of a needle.
