Your Pregnancy: Week 10
The roller coaster of nausea may almost be over, but the roller coaster of emotions (happy, sad, crying, mad; and that's all in the last 30 seconds) is just revving up. No one will understand why Friends reruns are making you cry, so don't bother trying to explain it.

Wondering what's up with your body, your baby and your life this week? Read on ...

What You're Thinking:
"Only 30 more weeks until I can eat raw fish and drink sake again."

Your Body
The hormones raging through your body can wreak havoc on your emotional sanity, so be prepared to spend the next few months swinging from one end of the emotional pendulum to the other. If you're feeling especially sad or depressed, talk to your doctor because prenatal depression is actually quite common.

Simple changes in exercise and diet have been proven to help women control depressive feelings. But if little things like sad songs and sappy commercials make you cry, don't worry, you're not alone. Wacky emotions can be chalked up to pregnancy hormones. So go ahead and blubber your way through Celine's greatest hits. It's OK.

Your Baby
By the end of Week 10, your baby graduates from embryo to fetus, which literally means "little one." It also translates to "I'm just going to keep getting bigger and bigger and so are you!" Other highlights this week:

Your baby has finally morphed from a little tadpole into, well, a baby. Not only is the face more human-like, but that unflattering "tail" (really just the developing spinal cord) has disappeared, fusing into the spinal column.

Your baby now has discernible fingers and toes, which will explain the steady stream of kicks and punches you'll feel down the line.

Junior's skeleton is starting to grow and harden. The ears are beginning to take shape and the eyelids are no longer transparent. Tooth buds are forming, although your baby won't get any teeth until six or seven (or eight or nine or 10) months after birth.

Baby's brain will make an incredible 25,000 new neurons every minute this week. While you may feel like you're losing as many as he's gaining, we can assure you it's not permanent. "Pregnancy brain," like nausea and bloating, is a temporary symptom that soon shall pass. (And then you'll get "Mommy brain," but we won't go there now.)

If you're baby is a boy, he's started producing that macho hormone testosterone. And whether your baby is a boy or a girl, the kidneys are creating copious amounts of urine. Lucky for you, you won't have to change a diaper for another 30 weeks.

Baby weighs only 4 grams and measures 1½ inches, about the size of a mondo Brazil nut.
