12/22 - 9 weeks, 4 days

At week's end, your fetus measures approximately 0.9 inches / 2.3 centimetres long. In both shape and size, it resembles a peapod and weighs less than a tenth of an ounce / 2 grams. The eyelids are fused and won't open until week 27. The wrists are more developed, ankles have formed, and the fingers and toes are clearly visible. Arms are growing longer and bend at the elbows. By week's end, the inner workings of the ears are complete. Though you can't yet identify the sex of the fetus by ultrasound, its genitals have begun to form. By now the placenta has developed enough to support most of the critical job of producing hormones.
