1) Ovulation Occurs
The time is right; now you just need this egg to be fertilized! Did you know that during your
pregnancy that your uterus will increase its capacity by 1000 times?
2) Gender Determined
Immediately upon fertilization your little one is set as a boy or a girl. Ladies, this is one that you can’t
take credit for since it is up to the sperm to determine the sex of your baby. Sperm carries
either a “X” (girl) chromosome or a “Y” (boy) chromosome.
3) Implantation
Implantation bleeding (spotting) may occur about 10 - 14 days after conception. You may believe you are starting
your period but generally this bleeding is extremely light and lasts only day or so.
4) Neutral tube forms
It will develop into the nervous system (Brain, spinal cord, hair and skin). Already your baby has the foundation for
though, sense, feeling and more!
5) Heart and primitive circulatory system form
While still in its beginning stages, this is the very life support system that will carry your child throughout his or her
life.
