What to Expect in the Second Three Months of Pregnancy

Second Trimester

In the second trimester of pregnancy, the fetus should now weigh about four to six ounces and be about four-and-a-half inches long. Its head may appear very large compared to the rest of its body and account for half the baby’s total length. Muscles have developed. The baby can move all its arm and leg joints.

Weeks 13 to 16

In weeks 13 to 16, your appetite will likely increase as morning sickness subsides. Your belly is probably beginning to show now and you will probably need to switch to maternity clothes and larger bras.

Weeks 17 to 21

Sometime between 18 and 22 weeks, you’ll begin to feel your baby move. This is called “quickening,” and is the beginning of what may be one of the greatest sources of joy during your pregnancy. It’s difficult to explain to a first-time mother exactly what she can expect to feel. Some women say it feels like a flutter in their lower abdomen or butterflies in their stomach. Others describe it as a bumping or nudging, a twitch, a growling stomach or a bubble bursting. Some first-time mothers mistake the first sensations of fetal movement for a gas bubble. Women who have had a baby before and recognize the sensation of fetal movement or women who are very thin may feel their baby’s first movement earlier than 18 weeks into their pregnancy.

In addition, a miscalculated due date can also make it appear as if the first movements are coming earlier in the pregnancy than normal. As your pregnancy progresses, your baby will be moving almost continuously, although you won’t feel every movement. The position of the fetus and your own activity can make your baby’s movements indiscernible. You may also be asleep when your baby is most active – as many babies are at their peak of activity in the middle of the night.

By the end of the fifth month, the fetus may be eight to 10 inches long and weigh between a half-pound and one pound. It has begun to grow hair on its head and its eyebrows and eyelashes begin to appear. A thick coating, called vemix, covers and protects the baby’s skin. The baby is becoming very active, and kicks. It can also open and close its eyes, and blink. Your uterus has grown to the height of your belly button, and you should now be able to feel your baby moving around inside. Because this is a very sensitive and emotional time, it’s important to be aware of your feelings and not bottle them up. Good communication with your partner, family and healthcare professionals can help alleviate your fears. So if you’re afraid of something, talk about it.

Weeks 22 to 27

Between the 24th and 28th weeks, fetal movement becomes more consistent and expectant mothers can keep track of fetal activity. If you’d like, or if your physician recommends that you do so, you can keep a “kick chart” that will track your baby’s movements. During this time, mood swings may occur and you may also experience feelings of “strangeness.” Hormonal changes in your body are the major cause of both. If you haven’t felt your baby moving around all day and you want to bring out some movement, try this in the evening: Have a glass of milk or a snack and lie down for an hour or two. The combination of your inactivity and the food may get your baby going. But don’t worry if it doesn’t work. Expectant moms may not feel movement for a few days at a time.

The rapid growth of your baby continues. The fetus should now weigh about one pound and be 11 to 14 inches long. Its skin is red and wrinkled and covered with a fine soft hair. Finger and toe prints are developing. You may feel your baby’s strong kicking and the skin on your belly is probably starting to itch. (Try cocoa butter or coconut oil.) You may also be experiencing pain down the side of your belly as your uterus stretches. Talk with your doctor about best remedies for pain. Don’t take any medications or supplements without consulting your doctor. What you take goes to your baby, too.

Stay Comfortable

Maintaining your comfort and safety is important while you’re pregnant, so be sure to take time to care for yourself. At the same time, be on the lookout for hazards that could potentially cause problems for you and your baby such as crowded stairways or hallways, or indoor or outdoor environments that have been cleaned or treated with toxic chemicals. By the end of the second trimester, your baby will begin to grow more rapidly and will demand a great deal of energy from your body. Here are a few tips to help you relax and replenish your energy:

  • Take a break every day for half an hour. For your break, gather six to eight pillows. Make a stack of four or five pillows in front of you. Make another stack of two or three pillows and sit on them, facing the larger stack. Lean forward onto the larger stack with the smaller stack supporting you. This will help take the weight of your uterus off your back and restore your energy.
  • Lying on your side can be an ideal resting position. This is especially important after your fifth month of pregnancy, when lying on your back can cause the weight of your enlarged uterus to impede the flow of blood and oxygen to you and your baby. For comfort, bend your knees and elbows. Then place several pillows under your knees, head and back.
  • Try semi-sitting to ease nausea and indigestion or make reading and relaxing more enjoyable. Lean back on pillows at about a 45-degree angle. Then put a pillow or a few rolled towels under your knees to give them support and keep them flexed.

Stay Safe

Here are ways to keep you and your developing baby safe in the second trimester:

  • Wear your seatbelt when in moving vehicles. Make sure you keep the lap portion of the belt under your belly, low and across your pelvic area. The shoulder harness should come down over your shoulder, between your breasts and over the top of your belly to fasten on the side. Follow your auto manufacturer’s recommendations for seatbelt and air bag safety. If you are driving, try to sit about 10 inches away from the steering wheel. And be sure to keep objects off your lap and the dashboard.
  • Watch out for workplace, household and garden chemicals. Fumes from paint, varnish, garden or home pesticides and cleaning fluids may contain dangerous chemicals you could inhale. This is a great time to make your home and gardens green spaces.
  • Stay away from hot tubs and saunas. The heat from these can damage your baby’s developing brain and spinal cord.
  • Avoid lead. Lead can be breathed or swallowed when found in paint, water and crystal.
  • Let someone else clean up after your pets. Cat feces can carry diseases that bring about birth defects.
  • Make a no-smoking rule in your house. Even second-hand smoke can hurt your baby.
  • Avoid caffeine, often contained in soda, coffee and tea.
  • Do not drink alcohol while you are pregnant or breastfeeding. It can result in serious mental and physical defects known as fetal alcohol syndrome.
  • Get your physician’s approval before taking any prescription or over-the-counter medications or home remedies.
  • Watch your step. You are not as well-balanced as you were before you became pregnant. Make sure your rugs have skid-proof bottoms and be careful getting out of the tub or shower.
  • Wear sensible shoes. Don’t wear high heels, sloppy slippers or thongs that could cause you to slip and fall.
