Your sense of taste and smell may also change. Your belly size, at this point, will remain mostly unchanged, however. Your baby, at this point, is still just a zygote, or a fertilized egg.

Half of it will turn into your placenta, which is the tissue that provides your baby with oxygen and nutrients while in the womb. The other half of the embryo becomes your baby. The neural tube will start to be formed at this point, and this will become your child’s backbone, spinal cord, and brain. None of this is visible yet, however, as the embryo is still classed as a zygote (fertilized egg).

Hi, I’m Stephanie. I graduated college with a business degree and a minor in biology. I met my husband at a business convention and was happily marriage and pregnant within the first two years after saying the words “ I do”.

Jennifer is the eldest of the three. Being pregnant with her, my first, I researched everything pregnancy related and read nearly every book. Giving birth to Anthony and Matty seemed more natural and less stressful the third time around.

I’m happy to share what knowledge I have gathered and learn new things from other mothers. From morning sickness to Anencephaly, or potty training to thumb sucking, I have books and resource guides to share.
