6w2d, 5 week review

From my weekly email (5week):  Deep in your uterus your embryo is growing at a furious pace. At this point, he's about the size of a sesame seed, and he looks more like a tiny tadpole than a human. He's now made up of three layers — the ectoderm, the mesoderm, and the endoderm — which will later form all of his organs and tissues.  The neural tube — from which your baby's brain, spinal cord, nerves, and backbone will sprout — is starting to develop in the top layer, called the ectoderm. This layer will also give rise to his skin, hair, nails, mammary and sweat glands, and tooth enamel.

His heart and circulatory system begin to form in the middle layer, or mesoderm. (This week, in fact, his tiny heart begins to divide into chambers and beat and pump blood.) The mesoderm will also form your baby's muscles, cartilage, bone, and subcutaneous (under skin) tissue.  The third layer, or endoderm, will house his lungs, intestines, and rudimentary urinary system, as well as his thyroid, liver, and pancreas. In the meantime, the primitive placenta and umbilical cord, which deliver nourishment and oxygen to your baby, are already on the job.

How far along? 6w2d
How big is baby? The size of a sesame seed
Symptoms? Pretty much none this week.  A few times I've gotten overly tired, but that's only happened two or 3 times.  Had one bout of nausea which passed in about 10 minutes.  Feeling less bloated.  Few cramps early in the week, but none now.  Having to go pee ALOT though.

Stretch marks? None
Maternity clothing? Nope
Sleep?  Sleeping well, but averaging getting up to pee 3-4 times a night
Exercise? So-so.  Ran a few times early in the week, but got lazy.  Did P90x twice
Cravings? Still just very thirty, adding to the peeing issue
Movement? No
Belly Button? Looks normal
What are you looking forward to this week? Telling the fam 4th of July weekend.  They will all be ecstatic (especially my mom).  Also our doctors apt set for next Friday.
