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: What are the signs of preterm labor?

What are the warning signs of preterm labor?

Re: What are the warning signs of preterm labor?

The Bump Expert

In general, it's important to be aware of the signs and symptoms of preterm labor as soon as they start, since your goal is to keep the baby (or babies!) in the womb, where they can continue to grow and gain strength until they are full term. Some of the signs to look out for if you think you're in pre-term labor include: vaginal discharge, loss of fluid or vaginal bleeding or spotting, pressure in the pelvis (or feeling like the baby is suddenly lower down), as well as tightening, contractions, or pain that is occurring regularly. While these are probably the most common symptoms, there can be others too. So if something doesn’t feel right (regardless of whether or not you can pinpoint it) you may want to contact your doctor just to be on the safe side. (There's definitely something to be said for that “sixth sense” moms are known to have about their babies!)
