Second Trimester Overview: Months 4, 5 and 6

Learn about changes and to-dos for weeks 14-27 of pregnancy.

August 18, 2025

Finding out you’re pregnant is such exciting news! For the next nine months, you'll go through a lot of changes. Although every pregnancy is different, this month-by-month guide can give you a sense of what to expect and help you feel more prepared along the way.

Month Four

Your Body

You may notice you have more energy. Nausea and fatigue may stop. You'll also notice your belly looks larger because the baby has grown.

Your Diet

During pregnancy, your need for iron increases. To be sure you get enough iron, eat lean, red meats, leafy green vegetables, whole grain breads, dried fruits and beans.

Childbirth Preparation Classes

Childbirth classes should begin in month seven. Register now since classes often fill up early.

Month Five

Your Body

Changes in your circulation mean you'll need stand and move often. Keep this up throughout your pregnancy. Your breasts may begin to leak a yellowish fluid called colostrum in preparation for breastfeeding. You may begin to feel the baby move during this month.

Your Diet

Be sure to eat food rich in vitamin C. Your body doesn't store vitamin C, so it's important to make sure you're getting some every day. Good sources of vitamin C are oranges, broccoli and tomatoes.

Choosing a Healthcare Provider for your Baby

Before you're admitted to the hospital, you need to decide who will care for your baby after the delivery. This is a good time to start looking for a healthcare provider for your baby. Talk to your friends and ask them if they're happy with the healthcare provider who cares for their children. Many pediatricians and family care physicians will meet with you before your baby is born so you can interview them. It's a good idea to select someone close to where you live.

Month Six

Your Body

You may gain 3 to 4 pounds this month. Your feet might swell during the latter stages of pregnancy. Putting your feet up may help reduce any ankle swelling. Shop for wide, comfortable shoes, preferably with a flat heel.

Your Diet

You may crave certain foods or find that other foods smell or taste bad, even if you liked them before you were pregnant. If this happens, try to find substitutes that provide the right nutrients.

Hospital Registration

If you haven't already registered at the hospital where you will deliver, it's a good time to do it. If you're delivering at a Sutter Health birth center, you can pre-register online. If you're delivering at a non-Sutter Health hospital, check with your healthcare provider or call the hospital directly for registration information.
