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.

Q&A: Choosing a prenatal vitamin?

Why do I need prenatal vitamins, and how do I pick the best kind?

Re: Why do I need prenatal vitamins, and how do I pick the best kind?

The Bump Expert

Your body simply has some extra needs when you’re pregnant, and vitamin supplements are the the best way to get in these essentials. Your own eating habits and physical condition play a big role in determining what supplements are right for you, but there are a few basics.

Folic acid is one of the biggies. This vitamin so drastically reduces the risk of neural tube defects like spina bifida that many doctors recommend every woman of childbearing age get at least 400 mcg each day. To keep up with your increased blood volume, you’ll also need more iron (at least 27 mg each day) during pregnancy. Extra calcium will help keep your own bones strong while your body is in the process of creating new ones for baby. Many women now also take an omega-3 fatty acid supplement like DHA, which helps baby's brain, nerve and eye tissue development. On the flip side, watch your intake of vitamins A,D,E and K -- these can be toxic in large amounts. The best way to find the right supplement for you? Take a good, honest look at your diet and talk with your doctor.
