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.
If you're like most women, you're feeling a bit more energetic now and your nausea may be starting to wane. Unfortunately, you may also be suffering from constipation (caused by hormonal changes, which can slow digestion) and heartburn (hormones again, relaxing the valve between your stomach and esophagus). Just remember, all this discomfort is for a good cause.
Don't worry if nausea has made it impossible for you to eat a wide variety of healthy foods or if you haven't put on much weight yet (most women gain just 2 to 5 pounds during the first trimester). Your appetite will likely return soon, and you'll start to gain about a pound a week.
