5 Weeks, 4 Days

Baby at 5 weeks.

At the end of the fifth week, the embryo is well fixed in the wall of the uterus. The future baby is no longer a fertilised egg, it has become an embryo.

The brain and the backbone begin to form.

The external covering changes also and begins to start the process of creating the placenta and the amniotic cavity (which will surround the placenta).

The heart is still being formed, but it already beats!

Baby's Profile: Size: - 0.2 - 0.5 mm

We finished spreading the word to various family members yesterday, and aside from my dad making the "glutton for punishment" comment, everyone seemed very happy. Even my dad said that he was at least happy that I was happy.

K's parents called with their congratulations today. They both sounded very happy, though K's mother pointed out several of the things that could go wrong at my age, noting that this should definitely be our last one. I'll concede that it's probably going to be our last one, but I'm not making any promises.
