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.

Why are my nipples darker?

My nipples are getting darker. What’s up with that?

The Bump Expert

It can seem like everything changes during pregnancy, even your skin. Some women get dark patches of skin on their faces -- or have a dark line that snakes up their bellies. And, yup, it’s normal for a woman’s nipples and areolas to become darker too.

No one really knows why the nipples darken during pregnancy. It might be that pregnancy hormones cause the cells that give our skin its pigmentation to become more active. In fact, darker nipples might be one of the first signs of pregnancy you notice, once those hormones start raging. Your nipples may keep getting darker as you get closer to delivery (maybe that’s nature’s way of making sure baby can find them when it comes time to breastfeed?).

Whatever the reason, nipple darkening is perfectly normal, and your nips will typically fade to your pre-pregnancy shade after birth.
