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!
This may help:
Human chorionic gonadotropin (hCG): The hormone released naturally early in pregnancy.
Progesterone: Female hormone related to the reproductive cycle.
Estrogen: A female reproductive hormone.
