Pregnancy - 5 weeks.

5 Weeks Pregnant 

Your embryo (at this tiny stage, she's still not technically considered a baby or even a fetus yet) is enjoying her first huge growth spurt. Although she still resembles a tadpole more than anything else, she's sprouting tiny buds that eventually will become arms and legs. Already her vital organs, including the heart, kidneys, and liver, are in place and growing. That's one good reason to pay close attention to your diet. Calcium-rich foods help bones, heart, and muscles grow - milk, cheese and tofu are all good sources.
