How your baby is growing
It’s unlikely that you are aware that you are pregnant at this early stage, however there have been monumental developments in your body! At some point roughly 1.5 – 3.5 million sperm took aim at your fallopian tubes and one persistent little seed hit the target spot on. The now fertilized egg is still inside your fallopian tube and is already merging with the sperm to become a zygote which will spend the next 7-10 days dividing and multiplying as it slowly descends into the uterus. When your little zygote is finally implanted it is a blastocyst measuring about 0.1 – 0.2 mm.

And how your life is changing
Your body is clever enough to recognizing this dynamic little zygote and is already producing Early Pregnancy Factor (EPF) protein, an immunosuppressant which will effectively keep your body from rejecting your growing zygote. You won’t feel nauseous or express any other of the main symptoms of pregnancy at this point, but if you’ve been planning this pregnancy and have been monitoring your morning basal body temperature, you will see that your temperature remains elevated beyond day 16 of your Luteal Phase (post ovulation). This will be the first physiological sign that you’re pregnant.
