3 weeks pregnant


3 weeks pregnant

Although you may not be feeling anything, by this week, you are most likely pregnant — congratulations! 

Your Child’s development
Only one in a million, the fastest of all sperms, wins in this crucial race about life and death. Once this sperm makes its way through the egg’s outer layer, fertilization happens. 

The zygote: The fertilized egg, also called the zygote, spends the next few days traveling down the fallopian tube to the uterus — a trip that takes about 5 – 6 days. 

The blastocyst: During this time, the zygote divides to form a ball of cells called a blastocyst. One single cell divides itself to become 2, which become 4, then 8, 16, 32 until the day Your Child develops into a full-grown baby.

Your development
If you were lucky and you’ve had sex during ovulation, your egg may have been fertilized by a strong sperm. If that happened, your body now starts to produce progesterone and estrogen. These pregnancy hormones are going to nourish and support Your Child until the placenta takes fully over at about week 10 of your pregnancy.

Things you can do
Eat fresh fruits that are high in vitamin C. This helps to increase your body’s absorption of iron, a nutrient your body needs to produce more blood and support Your Child’s development. Additionally, you can eat a lot of protein to help spur new tissue in the developing baby.

Please acknowledge
We are trying to be as accurate as possible, but, especially during the first 4 weeks of your child’s life, the medical and scientific community is not quite sure what exactly happens. So, despite great progress in the last 100 years, there are still many unknowns and many mysteries to be discovered. 

We, therefore, want to remind you to be mindful of the fact that the information presented might not be accurate or apply to your individual pregnancy or child.
