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: Leg cramps during pregnancy?

Why do I get leg cramps and how can I get rid of them?

Re: Why do I get leg cramps and how can I get rid of them?

The Bump Expert

You're not alone -- leg cramps (otherwise known as charley horses) are actually quite common during pregnancy and may signal one or two things: a lack of nutrients or dehydration. When your body doesn't have enough water or sodium, your muscles can contract; this is what you feel as a cramp. To prevent cramps caused by dehydration, be sure you're drinking between eight and 12 glasses of water a day. If water's not quite your thing, you can include milk, juice (avoid juice packed with sugar), sparkling water and decaf tea and coffee in the mix, too.

The other problem may be your diet. Drops in potassium, calcium or magnesium can all lead to muscle spasms. Now that you're pregnant, you should have 4,700 milligrams of potassium, 1,000 to 1,300 milligrams of calcium and 350 to 360 milligrams of magnesium per day.

Leg cramps tend to be more common (and painful!) in the third trimester. So if you haven't felt this yet, you may still -- just think of all that extra weight your legs are going to have to carry soon! In addition to eating and drinking right, there are some things you can do to limit those sharp pains in your calves. Stretching will keep your muscles more elastic and less likely to contract. Walking around and getting that blood flowing might help, too.

How should I sleep at night. Sideways? Is it safe to sleep facing up?

Q&A: Leg cramps during pregnancy?

I've seen different opinions online, but my OB told me to sleep any way that is comfortable. She said my body would discernably interfere and send signals making me very uncomfortable if blood flow is constricted by any particular position. I was happy to hear that...I am not too keen on side-sleeping, although it is starting to be the most comfortable lately. Sleeping on your back should be fine as long as it is comfortable!
