13 Weeks

Your baby has reached the size of a medium shrimp and weighs nearly an ounce. (Length: almost 3 inches, head to bottom.)

I had thought about omiting this image this week since I dislike all seafood. And what's with the shrimp when all of the other images are fruits or vegetables?

12 Weeks

Your baby is, by this time, the size of a lime and weighs 1/2 ounce. (Length: just over 2 inches, head to bottom.)

11 Weeks

Your baby is now about as big as a fig. (Length: just over 1 1/2 inches, head
to bottom.)

10 Weeks

Your baby, now barely the size of a kumquat, weighs less than a quarter of an ounce. (Length: a little over 1 inch, head to bottom.)

Nine Weeks

Your baby has grown to the size of a grape, weighs a fraction of an ounce, and is almost 1 inch long.

Eight Weeks

Your baby -- now comparable to the size of a kidney bean (just over 1/2 inch long) -- is constantly moving and shifting.

Seven Weeks

Your baby, having doubled in size since last week, is as big as a blueberry (about 1/2 inch in length).

Six Weeks

Your baby is as long as a lentil (about 1/4 inch).

Five weeks

Your baby has grown to the size of a sesame seed, looking more like a tiny tadpole than a human.

Four Weeks

Your baby -- now officially an embryo -- is about the size of a poppy seed.
