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.

33 Weeks Pregnant

We’d tell you to take a deep breath and relax, but it’s probably tough to do either of those at 33 weeks. It’s probably tough to be comfortable at all, since you might be feeling overheated on top of your other symptoms, too. But you’re probably getting super excited to meet baby, and we can’t blame you. Week 33 is a good time to make sure you have a safe car seat for baby -- go ahead and install it already. Sure, you might not see baby for another month, but if you have an early surprise arrival, that’s the one thing you really need to have ready.

Your baby's the size of a durian!
He weighs about 4.2 to 5.8 pounds and measures about 17.2 to 18.7 inches. And he may grow up to a full inch this week -- amazing.

your baby at 33 weeks
  • He's keeping his eyes open while awake.
  • He's also starting to coordinate breathing with sucking and swallowing.
  • His bones are hardening.
  • And he going through (more) major brain development -- that's one smart baby!
