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.

15 Weeks Pregnant

While baby’s moving a ton on the inside, you might be moving a ton -- between the sheets. Now that you’re at 15 weeks, you’re probably feeling very high energy, and that means high libido, too. Your partner isn’t feeling nearly as frisky? That’s totally normal too. Let’s face it, the thought of baby being so close while you two are, um, doing the deed, can freak a guy out. Remind him that baby has no idea what’s going on -- and, as long as your OB hasn’t given you any activity restrictions -- sex won’t hurt baby or threaten your pregnancy. Of course, you might be dealing with some not-so-sexy pregnancy symptoms during week 15, like nosebleeds, stomach issues and swollen gums, so if you’re not feeling up to sex, it’s completely understandable.

your baby's the size of a navel orange!
The average fetus at 15 weeks weighs 2.5 ounces and measures 4 inches -- and his proportions are becoming even more normal, since his legs now outmeasure his arms.

your baby at 15 weeks
  • You probably can't feel it yet, but she's squirming a ton!
  • She might even be hiccuping in there.
  • She's making lots of progress: her joints and limbs can all move now.

pregnancy symptoms at 15 weeks
  • Nosebleeds, thanks to increased blood volume and sensitive nasal passages.
  • Heartburn, gas and/or indigestion. More to blame on the hormones.
  • Frisky! Take advantage of the increased libido.
  • Swollen gums, another pitfall of those pregnancy hormones. Make sure you're taking care of your teeth, and see your dentist for your regular checkups.
