Understanding Each Trimester of Your Pregnancy

Learn how to navigate the first, second, and third trimesters.

You will encounter different experiences during each of your trimesters as your little miracle develops.

The First Trimester (0-13 Weeks):

During this period, your baby’s body structure and organs develop. Your body will also undergo major changes, and you may feel nausea, fatigue, breast tenderness and frequent urination. These are all common symptoms, but every woman has her own unique experience.

The Second Trimester (14-26 Weeks):

Many of the unpleasant symptoms of early pregnancy subside during this trimester. You’re likely to have increased energy and sleep better. However, some women experience back or abdominal pain, leg cramps, constipation or heartburn. Somewhere between 16-20 weeks, you may feel your baby’s first movements.

Third Trimester (27-40 Weeks):

You are now nearing the home stretch of your pregnancy and are probably very excited and anxious for the birth of your baby. Some of the physical symptoms you may experience during this period include shortness of breath, hemorrhoids, urinary incontinence, varicose veins, and sleeping problems. Many of these symptoms arise from the increase in the size of your uterus, which expands from approximately 2 ounces before pregnancy to 2.5 pounds at the time of birth.
