4 weeks PREGNANT!

Today I am 4 weeks pregnant! I am so thrilled and really nervous for my beta tomorrow to see that the number is doubling properly. Here is whats going on this week:

Right now your baby is an embryo the size of a poppy seed, consisting of two layers: the epiblast and the hypoblast, from which all of her organs and body parts will develop.
The primitive placenta is also made up of two layers at this point. Its cells are tunneling into the lining of your uterus, creating spaces for your blood to flow so that the developed placenta will be able to provide nutrients and oxygen to your growing baby when it starts to function at the end of this week.
Also present now are the amniotic sac, which will house your baby; the amniotic fluid, which will cushion her as she grows; and the yolk sac, which produces your baby's red blood cells and helps deliver nutrients to her until the placenta has developed and is ready to take over this duty.


  1. So happy for you! Yay for week 4- 36 to go! :)

  2. Congratulations Lindsey!!!! I'm so happy for you, that is wonderful news. Wishing you the best for the next 8 months. Kim
