9 Weeks Pregnant: Your Baby’s Development

No more tail. Your little one, now known as a fetus, is looking less and less like a pink blob now that the tail has disappeared. With the trunk straightened and elongated, your little one is about an inch long this week.

Growth spurt. This stage is a critical period for arm and leg development. The legs have lengthened and the buds that will eventually become the toes have started to sprout. Meanwhile, the arms have gotten longer and have begun to bend at the elbow. A basic hand structure is forming too, with the fingers and thumb clearly differentiated. Your little one's liver, gallbladder, spleen, and adrenal gland are starting to develop.

On the go. Nine weeks marks the beginning of the dance period! Your little one has started moving vigorously, even in response to stimuli from outside your body, such as light and noise. Try to be patient: You'll have to wait until the second trimester to actually feel these movements.

9 Weeks Pregnant: Your Symptoms

Make way for milk. Your breasts are probably fuller, heavier, and tender to the touch by now. Although they'll continue to grow throughout your pregnancy, the sensitivity will usually subside by the end of your fourth month. You may start to see small white bumps on your areolas (the dark-colored part of your nipple). These are glands called Montgomery's tubercles, and they'll produce oils to keep your nipples moist during breastfeeding.

Smooth moves. If you weren't active before you got pregnant, now is a great time to choose a safe activity you can stick with for the rest of your pregnancy. Swimming, walking, and yoga are all excellent choices.

Drop by the pool. Many experts consider swimming to be the best exercise for pregnant women, as it's gentle on your joints. The hormone relaxin that's now running through your body makes your joints loose so your pelvis can expand during birth. While this will help during your delivery, make sure to avoid exercises that could put too much strain on your joints in the meantime.
