According to the sites I follow, they each say something different about the size of the baby this week. Baby Center says the baby is the size of a fig, The Bump says the baby is the size of a lime and the book I have "Great Expectations: Your All-in-One Resource for Pregnancy & Childbirth" says the baby is the size of a peanut. But they all say the baby is about 1 1/2 inches long.
Here is the information I get from Baby Center via e-mail every week:
Your baby, just over 1 1/2 inches long and about the size of a fig, is now almost fully formed. Her hands will soon open and close into fists, tiny tooth buds are beginning to appear under her gums, and some of her bones are beginning to harden.
She's already busy kicking and stretching, and her tiny movements are so effortless they look like water ballet. These movements will become more frequent as her body grows and becomes more developed and functional. You won't feel your baby's acrobatics for another month or two — nor will you notice the hiccupping that may be happening now that her diaphragm is forming.
Sorry for anyone who isn't a fan of these types of photos (I wont post them often) but I find them interesting. This is 11 weeks:
