At 9 weeks your baby is approximately 0.9 inches long, and weighs approximately .07 ounces(about the size of a grape, green olive or cherry).
Would you believe your baby is only an embryo for one more week and is already developing into a fetus? Your baby’s head has straightened out and is more fully developed and the ears are continuing to grow. The eyes are fully formed, but her eyelids are fused shut. Plus, toes are visible, and all of baby's essential organs (heart, brain, kidneys, liver and lungs) have begun to develop, though they'll go through plenty of fine-tuning in the coming months. Your baby's heart finishes dividing into four chambers, and the valves start to form. The embryonic "tail" is completely gone. Your baby's organs, muscles, and nerves are kicking into gear. The external sex organs are there but won't be distinguishable as male or female for another few weeks. Your soon-to-be-fetus is also making spontaneous movements of the arms and legs now that minuscule muscles are beginning to develop. The placenta is developed enough now to take over most of the critical job of producing hormones. Now that your baby's basic physiology is in place, it’s poised for rapid weight gain.
Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
