Congratulations! Your baby has just been conceived! |
|
|
| • |
The fertilized egg starts to divide (multiplying by 2 each time), as it moves from the fallopian tube to the uterus. |
|
|
| • |
When it reaches the uterus, it is a ball of 32 cells, and it searches for a place along the uterus wall to implant itself. |
|
|
| • |
Towards the end of this week, the egg implants itself to the the outer lining of the uterus. It is now called a "blastocyst", and is mainly hollow and filled with fluid, barely visible in your uterus. |
|
|
| • |
By the end of this week, there will be around 250 cells in total. |
|
|
|
|
|
|
| • |
Once conception occurs, your body releases a substance called Early Pregnancy Factor to prevent your body from treating your baby as a foreign invader. |
|
|
| • |
After implantation, the blastocyst will secrete hormones that will cause your body to not shed the uterine lining (hence you will miss your next period). |
|
|
| • |
You might experience some spotting or bleeding at the time the blastocyst implants into the uterus. |
|
|
| • |
You probably won't be noticing any real changes in your body yet. |
