How your baby's growing: Your new resident is nearly an inch long — barely the size of a grape — and weighs just a fraction of an ounce, but he's poised for rapid weight gain now that his basic physical structure is in place. He's also starting to look more and more human. His embryonic "tail" is now completely gone and his body parts — including organs, muscles, and nerves — are kicking into gear.
His eyelids are fused shut and won't open until 27 weeks. He has earlobes, and by week's end, the inner workings of his ears will be complete. His upper lip is fully formed, too, and his mouth, nose, and nostrils are more distinct. The tips of his fingers are slightly enlarged where his touch pads are developing. All major joints — his shoulders, elbows, wrists, knees, and ankles — are working, enabling your baby to move his limbs. As for his heart, it has divided into four chambers now, and the valves have started to develop. External sex organs are there, but won't be distinguishable as male or female for another few weeks.

How your life's changing: You still may not look pregnant (although your belly will probably pop earlier if you've been pregnant before), but emotionally you may feel like you're on a roller coaster ride. Mood swings are common now; it's perfectly normal to feel alternately elated and terrified about becoming a parent. This feeling can persist throughout your pregnancy and well after your baby's born. Try to cut yourself some slack. Almost all expectant parents worry about how a new baby will change their lives, but the vast majority later say that becoming a parent was one of the best things they've ever done.
You may be feeling extra gassy or bloated now, too. That's primarily because the major doses of progesterone your body produces early in pregnancy relax smooth muscle tissue throughout your body, and that includes your gastrointestinal tract. This relaxation slows your digestive processes, which can cause more gas, bloating, burping, flatulence, and generally miserable sensations in your gut, especially after a big meal. Find out how to get relief.
