I'll be 5 weeks tomorrow, here's how big baby is!

I've started thinking of "him" as Johnny Appleseed after seeing this today. Here's what's going on:

"Your embryo (looking kind of like a tadpole) is starting to form major organs (heart, kidney, liver, stomach) and systems (nervous, circulatory, digestive). Baby's presence in your uterus triggers production of hCG (the hormone detected by pregnancy tests)... which triggers production of other hormones like estrogen and progesterone... which trigger all those great symptoms you've probably been noticing!"

"He's" still so tiny!
