Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

9 Weeks Pregnant

At nine weeks pregnant, you and baby have made two big accomplishments: You’ve made it to month three, and she’s no longer an embryo -- now she’s a fetus. Basically that means she’s becoming more and more baby-like, and you’re inching closer and closer to leaving the nasties of the first trimester behind you. Just one more month to go! By now, you’ve probably visited the OB, and maybe even seen baby’s tiny heartbeat on the ultrasound. Exciting stuff, huh? You’re also probably starting to think about how life will change when baby’s in the picture. Around week nine, you might want to start looking for ways you and your partner can budget, so you have some extra cash when she arrives. You also should consider checking out your company’s handbook to see how maternity leave is typically handled. That way, when it comes time to break the news to your boss, you’ll be prepared to discuss your expectations -- and begin a potential plan -- with her.

your baby's the size of a green olive!
She's gaining steam! At 9 weeks, your fetus measures around .9 inches and weighs about .07 ounces.

your baby at 9 weeks
  • This is a milestone. She's no longer an embryo -- now she's a fetus!
  • She's developing more distinct facial features.
  • And she might now have a strong enough heartbeat to be picked up by a fetal doppler.
